the rectangle is 54 square inches. What is the width of the rectangle
in inches?

Respuesta :

the tittle in usbfphwzo 88

Answer:

9

Step-by-step explanation:

Length: a

Width: b

ab = 54

a = b + 3

=> (b + 3)b = 54

=> b^2 + 3b = 54

=> b^2 + 3b - 54= 0

=> (b - 6)(b + 9)

=> b = 6 AND b = -9

Rectangular's sides > 0 => b = 6

Hope it's helpful :)
