Part of the roof of a factory is devoted to mechanical support and part to green space. The area of the roof R can be modeled by the polynomial 2x? - 251x + 80,000 and the area M, devoted to mechanical sup:
port. x + 224x + 31,250. Given that the area of the green space, G, is 123,750 square feet, write and solve
quadratic equations to find the dimensions of the green space.

Solve for x and use x to find the dimensions of green space.
