Question 1041076
The area of a rectangle in 48 in^2. It has w width that is 16 inches less than 4 times its length. 
What is the length of the rectangle? 
-----
Length = L 
Width = 4L-16
-------
Equation:
L(4L-16) = 48 in^2
------------------------
4L^2 - 16L - 48 = 0
------
L^2 - 4L - 12 = 0
---------
Factor::
(L-6)(L+2) = 0
-----
Positive solution::
Length = 6 inches
Width = 4L-16 = 24-16 = 8 inches
