The length of a rectangle is 3 meters less than twice its width.

a. write an equation to find the length of the rectangle.

b. the length of the rectangle is 11 meters. what us the width of the rectangle?

A.) Length= 2w-3 (w=width) 

B.) 11=2w-3

First, we add 3 to both sides... And we get
 14=2w

Next, we divide by 2 to get the w ( or width) by itself... and the answer would be 

7=w... So the width of the rectangle is 7meters

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
