Answer:
B
Step-by-step explanation:
Substitute x = 2 into f(x) , that is
f(2) = 3² + 4 = 9 + 4 = 13
Answer:
Mr. Meglio need to purchase 39 square feet of carpet.
Step-by-step explanation:
Given:
Total number of steps = 13
Length of each step = 1 foot
Width of each step = 3 foot
We need to find the square feet of carpet does Mr. Meglio need to purchase.
Solution:
First we will find the area of each step.
area of each step is equal to length times width.
framing in equation form we get;
area of each step =
Now amount of carpet required in square feet we multiply number of step with area of each step.
framing in equation form we get;
Amount of carpet required =
Hence Mr. Meglio need to purchase 39 square feet of carpet.

Answer:
yes, the polygons are similar. you can see this by the markings on the angles, this means that they have the same degree in the angles. the triangles are just dialated, or bigger, but they have the same degree in each angle
Step-by-step explanation:
Answer:2=c
Step-by-step explanation:
22=5c+3c-c+8
22-8=5c+3c-c+8-8
14=5c+3c-c+0
14=5c+3c-c
14=8c-2
14=7c
14/7=7c/7
2=c
Check answer by pluging 2 in for c.
5*2+3*2-2+8
=10+6-2+8
=16-2+8
=14+8
=22
The final answer is 2=c
