Answer:
c) x^6 y^11 z^6
Step-by-step explanation:
When multiplying exponents with the same variables, you add them.
so x^4(x^2) would be 4+2 and therefore x^6.
keep in mind this doesn't apply for different variables
(xy^2)(x^2y) will not be added!!

Comparing sides AB and DEAB =
[tex] \sqrt{ {1}^{2} + {1}^{2} } [/tex]
[tex] = \sqrt{2} [/tex]
DE
[tex] = \sqrt{ {(3 - 5)}^{2} + {(1 + 1}^{2} } \\ = \sqrt{ {( - 2)}^{2} + {(2)}^{2} } \\ = \sqrt{4 + 4} \\ = \sqrt{8} \\ = 2 \sqrt{2} [/tex]
So DE = 2 × AB
and since the new triangle formed is similar to the original one, their side ratio will be same for all sides.
scale factor = AB/DE
= 2
It's been reflected across the Y-axis
moved thru the translation of 3 units towards the right of positive x- axis
for this let's compare the location of points B and D
For both the y coordinate is same while the x coordinate of B is 0 and that of D is 3
so the triangle has been shifted by 3 units across the positive x axis

Quick questionnnnn :P
Answer:
44.
Step-by-step explanation:
Given expression: [tex]3t^2-t[/tex]
To find the value of [tex]3t^2-t[/tex] where t = 4, we need to substitute t for 4 in the expression.
After substituting, we use PEMDAS (the order of operations) to solve. This is because this problem includes multiple operations.
[tex]3(4)^2-4[/tex]
[tex]=3(16)-4[/tex]
[tex]=48-4[/tex]
[tex]=48-4=44[/tex]
[tex]\to \inft3(4)^2-4=44[/tex]
Therefore, the value of [tex]3t^2-t[/tex] is 44, when t = 4.

Joseph needs to calculate how much grass seed he needs to cover his lawn. A diagram of his lawn is shown below. One pound of seed covers an area of 100 square feet and the seed is sold in five-pound bags. How many bags will he need?
Joseph needs to buy 2 bags of grass seed as there are 6 pounds of seeds. Option G is correct.
Let us determine the total area of his lawn by multiplying its length and width.
Length of the lawn = 40 feet
Width of the lawn = 15 feet
Total area = Length × Width
= 40 feet × 15 feet
= 600 square feet
Now, calculate how many pounds of seed are required to cover 600 square feet.
One pound of seed covers an area of 100 square feet.
Therefore, we divide the total area by the coverage area of one pound of seed.
Total pounds of seed needed = Total area / Coverage area per pound of seed
= 600 square feet / 100 square feet
= 6 pounds of seed
Since the seed is sold in five-pound bags, Joseph would need to purchase at least 2 bags of grass seed (each bag containing 5 pounds) to cover his lawn.
Therefore, the correct answer is 2 bags. option G is correct.

How would you graph the solution set of x/6 ≤ -18
Multiply both sides by 6 and you'll end up with x ≤ -108
The graph will involve a closed circle at -108 and shading to the left
See below.
We use a closed circle to include the endpoint -108 itself. If we didn't have the "or equal to" part, then we'd be using an open hole at the endpoint instead.
The shading to the left is to describe values smaller than -108. Overall, the entire thing consists of stuff smaller than -108 or -108 itself.

What are the vertices of triangle A'B'C' if triangle ABC is dilated by a scale factor of 1/4
A ' (4,0)
B ' (6,3)
C ' (3,4)
================================================
Explanation:
I'm assuming the center of dilation is the origin.
If so, then we multiply the scale factor 1/4 = 0.25 by each of the coordinates of the three points.
Point A(16,0) will move to A ' (4,0) since
16*0.25 = 40*0.25 = 0Point B(24,12) will move to B ' (6,3) since
24*0.25 = 612*0.25 = 3We have enough information to see that choice B is the final answer
If you wanted to keep going, then point C(12,16) will move to C ' (3,4) for similar reasoning/steps as the previous two points.
The resulting image triangle A'B'C' will have its side lengths 1/4 of that compared to the side lengths of the preimage triangle ABC.
The scale factor k is such that 0 < k < 1, which indicates the image will be smaller compared to the preimage. If k > 1, then the image would have been larger than the preimage.

WILL GIVE BRAINLIEST AND THANKS. determine if these are tangent to the circle
Answer:
19 Five is not tangent to the circle.
20 Eight is tangent to the circle.
Step-by-step explanation:
In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.
I don't think the diagram on the left is, but I'll check it.
5^2 + 12^2 =
25 + 144 =
169
square root of 169 is 13
The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5 units long does not make a tangent to the given circle.
The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.
The radius and the distance to the external point form a right angle.
The Pythagorean triple is
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100

Answer:
2.75
Step-by-step explanation:
So to figure this out, lets start by converting it into a inproper fraction.
So we know that the whole number is 7, and the denominator is 16, so we need to multiply them together to make our fraction improper:
7*16
=
112
Now add the 9 from what we already had of the fraction:
112+9
=
121
So our improper fraction is:
121/16
Now we must find the square root.
So to find the square root of a fraction, you have to take the square root of both the numerator and the denominator.
The square root of 121 is 11. We know this because 121 is a perfect square, and 11*11 makes 121.
The square root of 16 is 4. We know this as well because 16 is also a perfect square, and 4*4 makes 16.
So the square root of 121/16 is now:
11/4
If you need to, you can convert this into a mixed fraction or a decimal.
4 goes into 11, 2 times with a remander of 3. So:
2 3/4.
3/4 is equivelent to 0.75, so this can also be:
2.75

Answer:

Step-by-step explanation:
The equation of the parallel line is y = x + 17.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
We are given that;
The table of line
Now,
The given line is shown in blue on the graph. We can see that it passes through two points: (0, 3) and (4, 7). We can use these points to find the slope of the given line:
m = (y2 - y1) / (x2 - x1)
m = (7 - 3) / (4 - 0)
m = 4 / 4
m = 1
The slope of the parallel line is also 1, since parallel lines have the same slope.
The point P is shown in red on the graph. We can see that its coordinates are (-8, 9). We can use this point and the slope to find the equation of the parallel line. We can use either slope-intercept form or point-slope form. We will use point-slope form here:
y - y1 = m(x - x1)
y - 9 = 1(x - (-8))
y - 9 = x + 8
y = x + 17
Therefore, by the given slope the answer will be y = x + 17.

find the exact value using a sum or difference identity of cos 105°
Answer:
Step-by-step explanation:
We can easily determine the exact value of this unknown angle by breaking it into known angles that can add together to give up 105. For example, 105 degrees is 60 + 45, both of which are found on the unit circle. We ill also use the trig identity for the sum of the cos of 2 angles which is:
[tex]cos(60+45)=cos60cos45-sin60sin45[/tex]
These values are found on the units circle, so make sure you have one handy. Those values fill in as follows:
[tex](\frac{1}{2})(\frac{\sqrt{2} }{2})-(\frac{\sqrt{3} }{2})(\frac{\sqrt{2} }{2})[/tex] which simplifies to

A. Distributive property of multiplication over addition
B. Multiplication property of equality
C. Commutative property of multiplication
D. Zero product property of multiplication
Answer:
D. Zero product property of multiplication
Step-by-step explanation:
The property of real numbers that Felipe used for step 2 is Zero product property of multiplication.
The zero product property of multiplication states that if any two factors of an algebraic expression is multiplied together and equated to zero, at least one of the expressions is equal to zero.
In the above question, factorising the algebraic expression above, we have two factors:
(x+2) and (x+4),
(x+2) (x+4) = 0
Hence,
x+2 =0 or X+4=

Angles = 50
Step-by-step explanation:
The angles are alternate interior angles and alternate interior angles are equal
4x+14 = 6x-4
Subtract 4x from each side
4x+14-4x = 6x-4-4x
14 = 2x-4
Add 4 to each side
14+4 = 2x-4+4
18 =2x
Divide by 2
18/2 =2x/2
9 =x
The angles are equal
4x+14 = 6x-4 = 4(9)+14 = 36+14 = 50
