Question

The dimensions of a rectangle are 2x - 5 and 2x - 5. Which expression represents the area of the rectangle in simplest terms?

Answer 1

Answer:

Step-by-step explanation:

(a - b)² = a² - 2ab +b²

Area of rectangle = length * width

                             = (2x - 5)(2x -5)

                             = (2x - 5)²

                            = (2x)² - 2*(2x)(5) + 5²

                             = 4x² - 20x + 25
