Question 971585
 On a rectangle, if the length is 5 less than 3 times the width, and the area is 112 cm, what is an equation to help you find the sides of the rectangle. 
-----------------
width = w
length = 3w-5
------
Area = width*length
------
w(3w-5) = 112
3w^2 - 5w - 112 = 0
------
(w-7)(3w+16) = 0
-------
width = w = 7 cm
---
length = 3w-5 = 16 cm
-------------
