Answer:
f(x) = 10x2 – 17x + 3
f(x) = 10x2 – 15x -2x + 3
f(x) = 5x(2x – 3) -1(2x - 3)
f(x) = (2x – 3)(5x -1)

Step-by-step explanation:
im not sure which is the length width height
but if length is 10
width is 3/5
height is 15
A=2(wl+hl+hw)=2·(0.6·10+15·10+15·0.6)=330

Identify the expression that has the largest value when a<-1
1-2a
a
a^2
a^3
Answer:
1-2a is the largest for -1 > a > -2.41
a^2 is the largest for -2.41 > a.
Step-by-step explanation:
We want to find the expression with the largest value.
Remember that the sign is important here, because:
1 is larger than -10
So we will look at the expressions that, when evaluated in a negative number, give a positive number.
The only two options in the case:
a < -1
are:
1-2a
and
a^2
So we have a linear equation and a quadratic equation.
We know that quadratic equations grow a lot faster than linear equations for all values larger than 1 (or minus one, because the sign does not matter).
if -1 < a < 1, a quadratic function grows really slow, but this is not the case.
So from now, we can guess that a^2 is larger.
But let's solve it graphically.
Let's define two functions:
f(a) = 1 - 2*a
g(a) = a^2
Now we can graph these two, and look at the region a < -1, and see which one is larger.
in the image, you can see that there is a small region from:
-1 > a > -2.41
Where the linear equation is larger, and for:
a < -2.41
The quadratic equation is larger.
Bryce tried to solve an equation step by step. \qquad\begin{aligned} \dfrac83&=3\left(c+\dfrac53\right)\\\\ \\ \dfrac83&=3c+\dfrac53&\green{\text{Step } 1}\\\\ \\ 1&=3c&\blue{\text{Step } 2}\\\\ \\ \dfrac13&=c&\purple{\text{Step } 3}\\\\ \end{aligned}
Answer:
Bryce is wrong in step 1 because he did not distribute 3 over 5/3
Explanation
Given the steps taken by bryce as shown, we are to find where he made an error
[tex]\qquad\begin{aligned} \dfrac83&=3\left(c+\dfrac53\right)\\\\ \\ \dfrac83&=3c+\dfrac53&\green{\text{Step } 1}\\\\ \\ 1&=3c&\blue{\text{Step } 2}\\\\ \\ \dfrac13&=c&\purple{\text{Step } 3}\\\\ \end{aligned}[/tex]
Given the expression;
[tex]\dfrac83&=3\left(c+\dfrac53\right)\\\\ \\[/tex]
Step 1:Expand the bracket using the distributive law;
8/3 = 3c + 3(5/3)
Simplify
8/3 = 3c + 15/3
Step 2: Subtract 15/3 from both sides
8/3 - 15/3 = 3c+15/3-15/3
(8-15)/3 = 3c
-7/3 = 3c
Step 3: Multiply both sides by 1/3
-7/3 * 1/3 = 3c * 1/3
-7/9 = c
Swap
c = -7/9
From the calculation, we can see that Bryce is wrong in step 1 because he did not distribute 3 over 5/3 thereby making his solution incorrect

The answer is 5 TRUST ME
Step-by-step explanation:
Answer:
5 is the median
Step-by-step explanation:
Median
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
Which side lengths do not make a triangle ?
10, 15, 23
1, 2, 4
5, 6, 7
6, 8, 9
Answer:
1,2,4
Step-by-step explanation:
Okay so basically in a triangle, the sum of any two sides should be greater than the third remaining side. So if we had a triangle with sides A, B, and C, A+B>c, A+C>B, and B+C>A. If you look at 1,2, and 4, 1=2=3 which is less than 4. That is why that is not a triangle.

Answer:
m∠ECD = 145°
m∠FCA = 35°
m∠PDF = 70°
Step-by-step explanation:
For ∠ECD:
- You can find this angle using supplementary angles. ∠ECD and ∠ECB are supplementary, meaning they add to 180°. Since the measure of ∠ECB is provided, you can subtract that from 180° to get m∠ECD:
180 - 35 = 145°, so m∠ECD = 145°
For ∠FCA:
- You can solve this problem using the Vertical Angles theorem. It states that vertical angles are congruent. ∠FCA's vertical angle pair is ∠ECB, which is 35°, so you can deduce that m∠FCA = 35°
For ∠PDF:
- You can find the measure of this angle by using supplementary angles like for ∠ECD. ∠PDC is supplementary to ∠PDF, and it's value is given. so you can find PDF by subtracting the value of ∠PDC from 180:
180 - 110 = 70°; m∠PDF = 70°

The bearing of a house from point A is 319° . From a point B , 317m due east of A , the bearing of the house is 288° , How far is the house from A ?.
Please show workings and a diagram.
Answer:
190.2 mStep-by-step explanation:
Refer to diagram in the attachment (not drawn to scale)
A and B are mentioned points and H is the home location.
Bearing on AH is 319°, the angle between horizontal line and AH is:
319° - 270° = 49°Bearing on ABH is 288°, the angle between horizontal line and BH is:
288° - 270° = 18°The 49° is the exterior angle, so the angle H is:
49° - 18° = 31°Use the law of sines to find x, the distance AH:
x/sin 18° = 317/sin 31°x = 317 sin18° / sin 31°x = 190.2 m (rounded)please answer I will mark brainliest

The three side lengths of four triangles are given. Which triangle is a right triangle?
Triangle 1: 13.6.7

Triangle 4: 10.9.8
Answer:
Triangle 1: 13.6.7
None of the triangles are right triangles.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
For a triangle to be a right triangle, the Pythagorean theorem must be satisfied.
So,
Applying the Pythagorean theorem.
Triangle 1:
13, 6, and 7
13² = 6² + 7²
169 = 36 + 49
169 = 85
Not true.
Triangle 2:
7, 8, and 13.
13² = 7² + 8²
169 = 49 + 64
169 = 113
Not true.
Triangle 3:
10, 11, and 12
12² = 10² + 11²
144 = 100 + 121
144 = 221
Not true.
Triangle 4:
10, 9, and 8
10² = 9² + 8²
100 = 81 + 64
100 = 145
Not true.
Thus,
None of the triangles are right triangles.

What is the equation of the line that passes through the point (−1,−5) and has a slope of −3?
Answer:
[tex]y=-3x-8[/tex]
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
1) Plug the slope (m) into the equation
We're given that the slope is -3. Plug -3 into the equation
[tex]y=-3x+b[/tex]
2) Solve for the y-intercept (b)
To solve for b, plug the given point (-1,-5) into the equation as (x,y).
[tex]-5=-3(-1)+b\\-5=3+b[/tex]
Subtract 3 from both sides
[tex]-5-3=3+b-3\\-8=b[/tex]
Therefore, the y-intercept is -8. Plug -8 back into our original equation as b
[tex]y=-3x-8[/tex]
