Question 741110: The area (in square inches) of a rectangle is given by the polynomial function A(x)=X^2+11x+18. If the length of the rectangle is (x+9) inches, what is the width? Answer by only4christ2(12) (Show Source):
You can put this solution on YOUR website! Simply factor the polynomial:
x^2 + 11x + 18 = (x + 9)(x + 2)
Since the length is (x + 9), then the width is (x + 2)
