Question

The length of a rectangle is 3 more than twice the width. Which of the following represents the length of the rectangle if the perimeter is 42 inches? 2(x) +2(2x+3)=42

Answer 1

Step-by-step explanation: if the width is x then the length is 2x+3

The perimeter is 2x+2(2x+3)=42

then 6x+6=42

6x=36

x=6

Then the length is 2*6+3=15
