Question

bailey writes the expression g2 14g 40 to represent the area of a planned school garden in square feet. if g = 5, what are the dimensions of the school garden? 20 feet by 2 feet 10 feet by 4 feet 12 feet by 7 feet 15 feet by 9 feet

Answer 1

To solve this, we must first factor g^2 + 14g + 40 to find the side lengths that are being multiplied. The factorization is (g + 4)(g + 10). Now that we have the factors, plug in 5 for g in each factor. So, the dimensions are 15 feet by 9 feet.
