Hiya! I have this confusing Math problem, can someone explain it to me?

5(x + 10) + x
A. 6x + 15
B. 5x + 15
C. 6x + 50
D. 4x – 50
I'm guessing the answer is A? But I'm just making a wild guess, so if someone could explain HOW to do the problem, I would be VERY grateful!
Thanks, and have a wonderful day!

review the distributive property.
5(x+10) + x
= 5*x + 5*10 + x
= 5x + 50 + x
= 6x + 50
