Question

The area of Mr.Birardis pool is 63x+81. If the width of his pool is 9,what is the length?

Answer 1

Answer:

The length is 7x+9

Step-by-step explanation:

We know that area equals length times width

A = l*w

63x+81 = l*9

The area is 63x+81 and the width is 9

Divide each side by 9

63x/9 +81/9 = 9l/9

7x +9 = l

The length is 7x+9

Answer 2

Answer:

The length should be 7x+9
