The length of a rectangle is 6 centimeters and its area is (6x + 18)square centimeters. Write an expression for the width.
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
Answer:
x+3=width
Step-by-step 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
