Sarah wants to hang a mirror in her room but the mirror and frame must not have an area larger than 15 square feet. The mirror is 3 feet wide and 4 feet long. Which quadratic equation represents the area of the mirror and frame combined? (The frame must have equal width of x on each side.) 3x2 + 14x − 2 = 0 4x2 + 14x − 3 = 0 x2 + 12x − 14 = 0 2x2 + 7x − 14 = 0

Well to find the area of a rectangle we do S + S x 2 or s•s + s•s so we have 3 +4 x 2 = x or 3 x 3 + 4 x 4 = x @lgbasallote Right-o?
