ASAP! GIVING BRAINLIEST! Please read the question THEN answer CORRECTLY! NO guessing. Show your work OR give an explaination.

Answer: A
I just love your questions. You always put "No guessing" haha.
Step-by-step explanation:
[tex]f(x)=3^x+10x\\g(x)=2x-4[/tex]
[tex](f+g)(x)=[/tex]
This basically means you have to take both functions and add them together.
[tex](f+g)(x)=(3^x+10x)+(2x-4)\\(f+g)(x)=3^x+10x+2x-4\\[/tex]
Combine like terms;
[tex](f+g)(x)=3^x+12x-4[/tex]
