Respuesta :
L = w+6
Perimeter = L + W
Substitute eqn 1 into 2
Perimeter = 2W + 6
Perimeter also = 8w
8w = 2W + 6
6w = 6
W = 1
Perimeter = L + W
Substitute eqn 1 into 2
Perimeter = 2W + 6
Perimeter also = 8w
8w = 2W + 6
6w = 6
W = 1
Answer:
The width is 3 inches.
Step-by-step explanation:
First, let's identify our variables.
L=Length
W=Width
P=Perimeter
P=2W+2L
We know that L=W+6
We can substitute L for W+6, and we can substitute P for 8W, which gives us the equation:
8W=2W+2(w+6)
If you go through all the steps to isolate the variable W, you'll end up with W=3
