G(x)= 33/x −x^2at x=a+b,

33/x - x^2 where x = a + b

33/(a + b) - (a + b)^2

d/da(33/(a + b) - (a + b)^2) = -2 (a + b) - 33/(a + b)^2

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
