A concert hall is in the shape of a rectangle. Its floor has a length of (x + 6) meters and a width of (2x - 3) meters.
Which of the following simplified expressions represents the area of the floor? A.) 2x² + 9x - 18 B.) 2x² + 15x - 18 C.) x² + 5x - 18 D.) x² + 9x + 18
Area of a rectangle = length x width
Area = (x + 6)(2x - 3) = 2x² - 3x + 12x - 18 {used FOIL method / distributive property} = 2x² + 9x - 18 {combined like terms} A.) 2x² + 9x - 18 Ask Algebra House Comments are closed.
