Answer:

4x^2 - 28x +48

Step-by-step explanation:

you would plug in h(x) into g(x)

(2x-7)^2 - 1 or (2x - 7)(2x - 7) - 1

solve (2x - 7)^2 using the foil method to get

4x^2 - 14x - 14x + 49

combine like terms to get

4x^2 - 28x + 49

now subtract 1 from 49 to get

4x^2 - 28x + 48

What is the solution of 2|2x-1|-8=18?

Maurinko [17]

Solve for $|2x-1|$ :

$2|2x-1|-8=18\implies2|2x-1|=26\implies|2x-1|=13$

Now if $2x-1\ge0$ , we have $|2x-1|=2x-1$ and

$2x-1=13\implies2x=14\implies x=7$

On the other hand, if $2x-1$ , then $|2x-1|=-(2x-1)=1-2x$ and

$1-2x=13\implies-2x=12\implies x=-6$
