If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f +9)(x) = 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:

its c or d   take a lucky guess my dude
