Answer:
B) 7x - 1
Step-by-step explanation:
In this question, you're going to solve by adding both f(x) and g(x) together.
You're finding (f+g)(x), meaning that you will be adding both of the equations to get your answer.
What (f+g)(x) looks like:
(5x - 2 + 2x + 1)(x)
What you would do is solve to get your answer. You're going to be combining like-terms and adding.
[tex](5x - 2 + 2x + 1)(x)\\\\\text{Combine the values with x}\\\\7x-2+1\\\\\text{Now you would finish by adding -2 and 1}\\\\7x -1[/tex]
When you're done solving, you should get 7x - 1
This means that B) 7x - 1 would be the correct answer.
I hope this helps you out.
Good luck on your academics.
Have a fantastic day!
