Answer:
f(x)=4x^2 and g(x)=-8x^2 + 4x - 4
(f+g)(x) = -8x^2 + 4x - 4 + 4x^2 = -4x^2 + 4x - 4 = -4(x^2 -x + 1)
(f+g)(-3) = -4( -3^2 -(-3) + 1) = -4 x 13 = -52
Hope this helps!

Answer:
Katie saved $20.
Step-by-step explanation:
I assume that "served" is a typo for "saved". Also, I assume that Tata and Ted are the same person.
Let the amount Katie saved = k
Then, ted saved $6 less than 4 times k, or 4k - 6.
The total saved by both is k + 4k - 6.
The total saved by both is $94.
k + 4k - 6 = 94
5k - 6 = 94
5k = 100
k = 20
Answer: Katie saved $20.
Once you do the math the answer will be
