A rectangle has an area of 12 square inches, and the length is 11 inches more than the width. Find the length and width of the rectangle.
If x represents the width of the rectangle, select all the equations that could be used to solve this problem.
---------------
width = x
length = x+11
----
Equation:
x(x+11) = 12
x^2 + 11x - 12 = 0
------
Factor::
(x+12)(x-1) = 0
Positive solution:
width = x = 1 in
length = x+11 = 12 in
