Part of the roof of a factory is developed to mechanical support and part to green space. THe area of the roof R of a larger building can be modeled by the polynomial 2x2-251x+80000 and the area of M roof that is devoted to mechanical support can be modeled by the polynomial x2+2241x+31250. The rest of the area is a rectangular green space. Given the area of G of the green space is 123,750 square feet, write and solve the quadratic equations to find the dimensions of the green space.

(x + 125), (x - 600)

Step-by-step explanation:

The objective is to write and solve the quadratic equations to find the dimensions of the green space.

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
