the length of a rectangle is 6 inches, and the width is 5 inches. when each dimension is increased by x inches, the area triples. which equation models this situation?
Before the increase, the length is 6 and the width is 5, so the area is 5×6 = 30.
After the increase, the length is x+6, the width is x+5, and the area is tripled: 30×3 = 90.
Therefore:
(x+6) (x+5) = 90
