Question

Which expression represents the perimeter of the rectangle above?

A. 6x+2
B. 12x-8
C. 6x-4
D. 12x+2

Answer 1

Explanation:

the perimeter is : P= 2 (L+W) .... L : the length W : the width

P =2 (3x-1+3x-3)

P= 2(6x-4)

P= 12x-8 ....answer B

Answer 2

B (12x - 8)

Explanation:

Simply multiply both of the equations (3x -3) and (3x - 1) by 2 so you would have (6x -6) and (6x - 2) add them both together and you get 12x - 8
