Question 1206274
<pre>
Lawrence is increasing his rectangular patio in his backyard. His patio is currently 12 feet by 10 feet. He wants to increase the patio by adding a decorative tile the same width (x) all the way around creating a total area of 180 square feet. Select all the quadratic equations that represent Lawrence’s new patio area.
A  x^2 + 11x − 15 = 0
B  x^2 − 11x − 15 = 0
C  x^2 + 22x − 60 = 0
D  x^2 − 22x − 60 = 0
E  4x^2 + 44x − 60 = 0
 4xx2 − 44xx − 60 = 0

(12 + 2x)(10 + 2x) = 180
FOIL and simplify to form a quadratic equation.
