Question

The length of a rectangle is 6 centimeters and its area is (6x + 18)square centimeters. Write an expression for the width.

Answer 1

x+3=width

Explanation:

area=length times width

length=6

area=6x+18

substitute

6x+18=6 times width

undistributed 6 from each term on left side

6(x+3)=6 times width

divide both sides by 6

x+3=width

Answer 2

area=legnth times width
legnth=6
area=6x+18
subsitute
6x+18=6 times width

undistribute 6 from each term on left side
6(x+3)=6 times width
divide both sides by 6
x+3=width
