The correct answer is 4a^2 + 3ab
In order to find this, we can write the equation out as described and then follow the order of operations.
3a^2 - 2ab + 3b^2 - (-a^2 - 5ab + 3b^2) ----> Distribute the negative
3a^2 - 2ab + 3b^2 + a^2 + 5ab - 3b^2 ----> Combine like terms
4a^2 + 3ab

Answer:
f(x)=740
Step-by-step explanation:
f(x)=45x+200
If f(12)
f(x) = 45(12) +200
f(x) = 540 +200
f(x)=740
First one is 6 and the second one is 21
