Answer:

x = -3

Step-by-step explanation:

x + 2 and -x-4 is equal, because they are both y

we want to move the variables to one side and the numbers to the other side

x+x = 2x, and -4-2 = -6

so 2x = -6

and x = -3

Rectangular field has a total perimeter of 128 feet. The width is

dsp73

Answer:

<h3>The length is 44 feet</h3><h3>The width is 20 feet</h3>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

Perimeter = 128 feet

The width is 24 feet less than the length is written as

w = l - 24

128 = 2l + 2( l - 24)

128 = 2l + 2l - 48

Group like terms

4l = 176

Divide both sides by 4

l = 44

The length is 44 feet

Substitute l = 44 into w = l - 24

w = 44 - 24

w = 20

The width is 20 feet
