Answer:

the answer for the first one is 141

and the answer for the second is 48

Answer:

First: -1628

Second: -16

Step-by-step explanation:

For the first problem, start by rewriting the equation by plugging in h and g as (4n-3)(-4n-4)

By FOILing this, you’ll end up with -16n^2-16n+12n+12
-16n^2-4n+12

Now you can plug in n, which is -10:

-16(10)^2-4(10)+12

-1600-40+12

-1628

For the second question, you’ll be plugging f(-2) into g, but I’ll leave -2 as n for simplicity until the end

g(n)=n^2+2n

f(n)=2n-4

g(n)=(f(n))^2+2(f(n))

(2n-4)^2+2(2n-4)

(4n^2-16n+16) + (4n-8)

4(-2)^2-16(-2)+16+4(-2)-8

16-32+16-8-8

-16
