Question

One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54 inches.
Which of the following equations could be used to determine the dimensions of the rectangle?
2x + 2(x - 3) = 54
2x + 2x - 3 = 54
2x - 3 = 54

Answer 1

one side=x

other=x-3

perimeter =54

(x-3)*2 +(x)=54 this is equal to first one so thats the answer

2x-6+2x=54

4x=60

x=15

Answer 2

(x-3)*2 + 2*(x)=54 missed the 2 *

Answer 3

so the second or first one?

Answer 4

first.

Answer 5
