Answer:
Step-by-step explanation:
perimeter of a rectangle = twice the length plus twice the width
P = 2L + 2W equation 1 P = 86 ft
Given the length is seven feet more than the width
L = W + 7 equation 2
Substitute equation 2 into equation 1
P = 2(W+7) + 2W = 86 ft
2W +14 + 2W = 86 ft
4W = 86 - 14
W = 72 / 4
W = 18 feet
Answer
<h2>
4</h2>
Step-by-step explanation:
Given,
r = 10
Let's create an equation,

plugging the value of r

Multiply the numbers

Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.

Calculate

The difference sign ( - ) should be cancelled on both sides

Divide both sides of the equation by 5

Calculate

The value of s is 4.
Hope this helps..
Best regards!!
