A rectangle has a length that is 5 inches greater than its width, and its area is 104 square inches. The equation (x + 5)x = 104 represents the situation, where x represents the width of the rectangle.The first step in solving by factoring is to write the equation in standard form, setting one side equal to zero. What is the equation for the situation, written in standard form?
Expand the left side: (x + 5)x = x² + 5x. To write the equation in standard form with one side equal to zero, subtract 104 from both sides, giving x² + 5x − 104 = 0. This is choice D, x² + 5x − 104 = 0.
