31 doesn't have a factor of 11 or 3 so it is simplest form
also, 31 is prime so it can't be factored
(A) find it’s average rate of change by changing x=1 to x=5
Answers
Answer: I really don’t know
Step-by-step explanation: I need help with this as well. I’m really sorry if you were looking for a real answer
Final answer:
The average rate of change of the function f(x) = 6x +5 over the interval x = 1 to x = 5 is calculated with the formula Δf/Δx and is found to be 6.
Explanation:
In the given function, f(x) = 6x + 5, the average rate of change is calculated by the formula Δf/Δx, which refers to the change in the function value over the change in the x-value. Plugging in the given values, we have:
Δf = f(5) - f(1) = [6(5) + 5] - [6(1) + 5]
Δx = 5 - 1
So, the average rate of change is Δf/Δx = [30 + 5 - 6 - 5]/(5 - 1) = 24/4 = 6.

Final answer:
To find EG, we equate EF to EG and solve for x. Substituting the value of x back into EG gives us a final answer of 22.5.
Explanation:
In the given question, F is the midpoint of EG. We are given that EF = 5x and EG = 7x + 5. To find the value of EG, we need to equate EF to EG and solve for x.
Given: EF = EG = 5x
Substituting the values, we get: 5x = 7x + 5
Simplifying the equation: 2x = 5
Dividing both sides by 2, we find: x = 2.5
Now, substituting the value of x back into EG, we get: EG = 7(2.5) + 5 = 17.5 + 5 = 22.5
Therefore, EG is equal to 22.5

B. 1/8
C. - 1/8
D. 8
Answers
Answer:
the answer is -1/ 8
Step-by-step explanation:
(−2−6)(23)
=(−1/64)(2x3)
=−1/64 (2x3)
2x2x2= 8
-1/64 8/8
Now you divide both sides by 8
-1/64 / 8/8= -1/8
So your answer is −1/8(C)
hope it helpsssssss :)

first, the coeieicne infront of x^2 term musbe 1
so if you have

What is the effect on the perimeter when the dimensions are multiplied by 8?
The perimeter is increased by a factor of 8.
The perimeter is increased by a factor of 24.
The perimeter is increased by a factor of 64.
The perimeter is increased by a factor of 256.
This figure is made up of a triangle and a semicircle.
What is the area of this figure?
Use 3.14 for pi. Round only your final answer to the nearest tenth.
Enter your answer, as a decimal, in the box.
Answers
the area is 7 square feet
when calculating the area the scale factor is squared as well.
since the scale factor is 16, to find out area the scale should be squared that is,
16*16 = 256
then the new area is 7 square feet * 256
actual area = 256 * 7 = 1792 square feet
Q2. the rectangle with length 6 inches and width 3 inches.
the perimeter of the rectangle before changing dimensions are;
=(6*2) + (3*2)
= 12 + 6 = 18 inches
after multiplying the dimensions by 8,
new length = 6*8 = 48 inches
new width = 3*8 = 24 inches
new perimeter = (48*2) + (24*2)
= 96 + 48
= 144 inches
the perimeter ratio from new to old = 144:18
the perimeter has increased by (144/18) times
= 144/18 = 8
answer is perimeter increased by a factor of 8
q3)
area of the triangle
= 1/2 * height * base
= 1/2 * (5-2) *(4-(-3))
= 1/2 * 3 * 7
= 10.5 units²
area of semicircle
=pi*r2
r = 2-(-1.5)
= 3.5
area = 3.14 * (3.5)²
= 38.465 units²
total area = area of triangle + area of semicircle
= 10.5 + 38.465
= 48.965
round it off to the closest tenth
area = 49 units²
