Apply the distributive property to factor out the greatest common factor.

alexgriva [62]

Answer:

Step-by-step explanation:

Remark

I take it that 24 is in front of j which means that the term is 24j. There shouldn't be a comma there.

24 = 8*3
16 = 8*2

Both numbers have 8 in common, and that's all they have in common. The GCF is therefore, 8

24j - 16 = 8(3j - 2) That's the answer.

Answer: 8 (3j - 2)

If g(x)=7x²−4x−3 and h(x)=5x²−12x, find (h∘g)(1) FIRST BEST ANSWER BRAINLIEST

AURORKA [14]

Answer: See below

Step-by-step explanation:

$h\:\circ \:g=h\left(g\left(x\right)\right)$

$=5\left(7x^2-4x-3\right)^2-12\left(7x^2-4x-3\right)$

$=5\left(7x^2-4x-3\right)\left(7x^2-4x-3\right)-12\left(7x^2-4x-3\right)$

$=245x^4-280x^3-130x^2+120x+45-84x^2+48x+36$

Simplify:

$=245x^4-280x^3-214x^2+168x+81$
