Question

I need help !!!!!
Can some one tell me how to solve + answer

Answer 1

x^2 + 23x + 49

Explanation:

Area of rectangle = (x + 10)(2x + 5) = 2x^2 + 25x + 50

Area of square = (x + 1)(x + 1) = x^2 + 2x + 1

Area of shaded region = area of rectangle - area of square

A = (2x^2 + 25x + 50) - (x^2 + 2x + 1)

A = 2x^2 - x^2 + 25x - 2x + 50 - 1

A = x^2 + 23x + 49

Hope this help.
