Question

1. The length of a rectangle is twice the width. An equation that models the perimeter of the rectangle is 2​w +​ 4​w =​ 36 where ​w ​is the width of the rectangle in ft. What are the length and the width of the rectangle?
2. Two consecutive odd integers can be modeled by ​n ​and ​n +​ 2, where n ​is
an odd integer. The sum of two consecutive odd integers is 80. What are the
integers?

Answer 1

1. 6w = 36
w = 6 l = 12

2. n + n + 2 = 2n + 2 = 80
2n = 78
n = 39 n+ 2 = 41
