Question

A rectangle has side lengths (x +5) feet and (2x−3) feet. Write a linear expression in simplest form to represent the perimeter. Find the perimeter if the value of x is 6 feet.

Answer 1

Answer:

6x+4 ft

40 ft

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

  = 2( x+5 + 2x-3)

Combine like terms

  = 2(3x+2)

 Distribute

  =6x+4

Let x= 6

 = 6*6+4

  = 36+4

  = 40
