Answer:
2x^2 +11
Step-by-step explanation:
f(x) = 3x^2 +2
g(x) = x^2 -9
f(x) - g(x) = 3x^2 +2 - (x^2 -9)
Distribute the minus sign
= 3x^2 +2 -x^2 +9
Combine like terms
= 2x^2 +11
1/3x + y = 4....subtract 1/3x from both sides
y = -1/3x + 4 <===
50.24
4 squared is 16
16•3.14= 50.24
A= 3.14(4)^2
:)
I believe it is 6 because u just divide 24 by 4
