mary wants to fence in a rectangular run for her dogs. she has decided that the run will be 5 yards wide.

which statement best describes the possible lengths of the run if she can use no more than 40 yards of fencing?

a. at most 8 yards
b. at most 15 yards
c. more than 8 yards
d. more than 15 yards

So, the perimeter total is 40
to find the perimeter we add all of the sides together
We know all of the sides, these sides should add up to 40

So the equation that we have should look somewhat like this.

5+5+x+x=40

We want to isolate x, to do this we should first combine like terms, the equation is now

10+2x=40
We'll then subtract 10 from both sides, the equation is now.

2x=30

We will then divide both sides by 2
2x/2= x
30/2= 15

x=15 is the final equation

So at most she can use 15yds of fencing for the length.

So your answer is
B. at most 15 yards

A
