Hey there!
Your answer is:
[tex]\boxed{B. 11+x}[/tex]
Both terms x and 11 are positive, so we can't have C or D. They both subtract something, have negative signs.
11x is x times 11, not x plus 11. It's 11 x's, not x and 11. So A is incorrect.
B is correct. It is two separate terms, both positive, added together.
Hope this helps!
