PLEASE HELP ME IT WOULD MEAN A LOT

12x³ - 3x

Step-by-step explanation:

Given

f(x) = x and g(x) = 4x² - 1

Now,

3 f(x) * g(x)

= 3 * x (4x² - 1)

= 3x ( 4x² - 1 )

= 12x³ - 3x

Hope it will help :)

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:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
