Answer:
10
Step-by-step explanation:
g(f(x)) = g(3x² - 4) = 2(3x² - 4) - 6
so
g(f(2) = 2(3*2² - 4) - 6 = 2*8 - 6 = 16 - 6 = 10
Multiplication would be first
F(x)= x+13
F(-2)= -2 +13
= 11
You plug in -2 for the x
Das is 20 points per user, just fyi
1. distributive property
recall that a(b+c)=ab+ac
5(3x-4)=5(3x)+5(-4)=15x-20
2. bruh, I can't show that here, wait, nvm, see attachment

3.
100% is double the price
45*2=90
the item will sell for $90 in store
4.
1/2+1/4+1/8=
4/8+2/8+1/8=
7/8
7/8 piazza was eaten
5. see attachment
it ends at 15
Sum refers to addition and difference refers to subtraction.
