(f+g)(x)=2x+1+x^2-7
(f+g)(z)=x^2+2x-6
Given:
L = W - 4
P = 2L + 2W
We can substitute 2L for 2(W - 4) = 2W - 8
So:
2W - 8 + 2W = P
P = 4W - 8
Answer is 4. 4W-8
f(5) is when X is equal to 5, so look at the table find X 5 then see what the f(x) value is:
When X is 5, f(x) is -8.
The answer is -8

Answer:
(-2,4)
Step-by-step explanation:
