The area of the roof of a large building is modeled by the function fR (x) = 2? - 251a + 80, 000 and the area of the roof that is devoted to mechanical support is given by the function fM (x) = x² + 224x +31, 250. Given that the area of the green space is 123,750 square feet, find its dimensions.

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
