Answer:

x = 8

Step-by-step explanation:

Given

- 8(- x - 7) = 120 ( divide both sides by - 8 )

- x - 7 = - 15 ( add 7 to both sides )

- x = - 8 ( multiply both sides by - 1 )

x = 8

Answer:

W = 16 in

Step-by-step explanation:

P = 2L + 2W

56 = 2(12) + 2W

56 = 24 + 2W

56-24 = 2W

32 = 2W

W = 32/2

W = 16 in

The perimeter of a rectangle is 96 feet. Three times the width is 8 less than the length. Find the dimensions of the rectangle.
Roman55 [17]
Width= w
length= (3w-8)

2w+2(3w-8)= 96
2w + 6w -16= 96
8w= 112
8w/8= 112/8
w= 14

width= 14 feet
length= 34 feet

so the dimensions are 14x34 feet
