Question

The perimeter of a rectangular wooden deck is 90 feet. The deck's length, l, is 5 feet less than 4 times its width, w.

Which system of linear equations can be used to determine the dimensions, in feet, of the wooden deck?
Responses
A 2l + 2w = 90

l = 4w - 52 l + 2 w = 90 l = 4 w - 5
B 2l + 2w = 90

l = 5w - 42 l + 2 w = 90 l = 5 w - 4
C 2l + 2w = -5

l = 4w - 902 l + 2 w = -5 l = 4 w - 90
D 2l - 2w = 90

l = 4w + 5

Answer 1

B 2l + 2w = 90

l = 5w - 42 l + 2 w = 90 l = 5 w - 4

Answer 2

are u sure thats right?
