2. the width of a rectangle is 3 feet shorter than its length. the perimeter is 530 feet. let x equal the length of the rectangle. the formula is p = 2l + 2w. what are the length and the width of the rectangle?

  length: 134 ft; width: 131 ft

Step-by-step explanation:

If x is the length of the rectangle then x-3 is the width and the perimeter is ...

  530 = 2x +2(x-3) = 4x -6

  536/4 = x = 134 . . . . . . . . add 6 and divide by 4

The length of the rectangle is 134 ft; the width is 131 ft.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
