The width of a rectangle is 1 unit less than the length. The area of the rectangle is 72 units. What is the width, in units, of the rectangle?

Step-by-step explanation:

Width of the rectangle= W

Length= L

W=(L-1) units

Area= 72 square units

Area of a rectangle= Length*Width

Solving the quadratic equation using the factorization method:

Taking common from the equation:

OR

The length cannot be negative, therefore: Length= 9 units

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

not sure but it may be b, as i said i'm not sure.
