Answer:
(2x + 1)(x + 5).
Step-by-step explanation:
`y=2x^2+11x+5`
2 * 5 = 10
1 * 10 = 10 and 1 + 10 = 11 so we write:
y = 2^2 + 10x + x + 5
y = 2x(x + 5) + 1(x + 5)
= (2x + 1)(x + 5).

Actually Welcome to the concept of areas,
we know that, area of rectangle = length * width,
here, length = x-2 and width = x-1
hence, area = (x-2) (x-1)
==> area = x^2 -x -2x +2
==> Area = x^2 - 3x + 2
hence the Option D.) is correct

Step-by-step explanation:
its a pattern if you look at the trend on the equation
The seniors and juniors at Sweet Valley High School are going on a trip to Busch
Gardens. The seniors filled 12 vans and 12 buses with 564 total students. The juniors
filled 6 vans and 13 buses with 492 students. How many students were in each van? In
each bus?
Solve the system of equations
Answer:
buses can hold 30 and vans can hold 17.
Step-by-step explanation:
Let the amount a van can hold be v and the amount a bus can hold be b.
12 vans and 12 buses totals 564: 12v + 12b = 564 (equation 1)
6 vans and 13 buses totals 492: 6v + 13b = 492 (equation 2)
Subtract 2 times equation 2 from equation1, we get 14b = 420.
Thus, b = 30.
Since 12v + 12b = 564, plugging in b=30, 12v + (12)(30) = 564, so v = 17.
The number of students filled in the van is 17, and number of students filled in the bus is 30.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the total number of students in van is x, and the number of students in the bus is y
Now for the first scenario we can frame a linear equation in two variables such as:
12x + 12y = 564 or
x + y = 47 ....(1) (divide by 12 on both sides)
For the second scenario the linear equation in two variables becomes:
6x + 13y = 492 ....(2)
From the equation (1) take the value of x and plug in the equation (2), we get:
6(47-y) + 13y = 492
282 - 6y +13y = 492
7y = 492-282 (subtract 282 from both sides)
7y = 210
y = 30
Put this value in the equation (1), we get:
x + 30 = 47
x = 17 (subtract by 30 from both sides)
Thus, the number of students filled in the van is 17, and number of students filled in the bus is 30.

Carmen had
of a spool of yarn. She used
of her yarn for a project. What fraction of the spool was used for the project?
Write your answer in simplest form.
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
Please help me with this homework
Answer:
20km
Step-by-step explanation:
we need to find c, which is the hypotenuse of the right triangle.
we know the lengths of the legs, which are given as 16km and 12km
you might notice that 16km and 12km can both be divided by 4, which will then give is 4 and 3.
3,4,5 is a pythagorean triple-(the sums of the squares of 3 and 4 is equal to the square of 5).
The triple can be proved:
3²+4²=5²
9+16=25
25=25
that means the lengths of the triangle is a multiple of the triple 3, 4, and 5
so that means that c is 5*something
since 12 and 16 are 3*4 and 4*4 respectively, that means that c must be 5*4=20km
Hope this helps!
In a school the number of students with blonde hair to the numberof student with brown hair is 4:5 what fraction of students have blonde hair
Answer:

Answer: its cubic
Step-by-step explanation:
The graph below is an example of a cubic type of function. Option C is correct.
What exactly is a function?A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.
1. A parabola is the graph of a quadratic function. As a result, the presented graph is not a quadratic function graph.
2. A straight line is represented by a linear function. As a result, the presented graph is not a linear function graph.
3. A cubic function's end behavior is opposite at both ends. We can see that the presented graph satisfies these requirements.
4. A square root function's graph resembles a half parabola. As a result, it can't be the graph of the square root function.
The graph below is an example of a cubic type of function.
Hence,option C is correct.

Solve 6f-4g=1,6f-6g=5
Answer:
The solution is (-1/2, -2)
Step-by-step explanation:
Given 6f-4g=1,6f-6g=5, write these in columnar form:
6f-4g=1
6f-6g=5
Change all of the signs in the first equation:
-6f + 4g = -1
6f-6g=5
-------------------
-2g = 4, and so g = -2
Substituting -2 for g in either equation enables us to find f. Let's use the first equation: 6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3
Then f = -1/2 and g = -2. The solution is (-1/2, -2)

Answer:
9442 lb
Step-by-step explanation:
First find the volume of the tank. This being a sphere, the volume is V =(4/3)π·r³. Here the diameter is 17 ft, so the radius, r, is half that: 8.5 ft.
Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.
Water weighs 62.4 lb/ft³. To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:
×
(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb

Answer:
V = (4, 4 )
Step-by-step explanation:
Use the midpoint formula, the equation corresponding coordinates to the coordinates of the midpoint M
let V = (x, y ) , W = (8, 6 ) , then
[tex]\frac{x+8}{2}[/tex] = 6 ( multiply both sides by 2 )
x + 8 = 12 ( subtract 8 from both sides )
x = 4
and
[tex]\frac{y+6}{2}[/tex] = 5 ( multiply both sides by 2 )
y + 6 = 10 ( subtract 6 from both sides )
y = 4
coordinates of V = (4, 4 )
