G(x)= -3x(x-8), find g(-4)

g(-4)=144

Step-by-step explanation:

g(-4)=-3*-4)(-4-8)

3*-4=-12

-4-8=-12

-12*-12= 144

g ( 8 x ) = 8 x + 8

Step-by-step explanation:

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:
