Answer: B) 11x^2

Step-by-step explanation:

Choice A combines to 11x since the 8+3 simplifies to 11.

Choice D is a very similar story. Think of having 8 boxes, which we denote in shorthand as 8x. Then adding on 3 more boxes leads to adding on 3x. Having 8 boxes plus another 3 boxes gives 8+3 = 11 boxes total. So that's why 8x+3x = 11x. Alternatively, we can factor out the x to say 8x+3x = (8+3)x.

This shows choices A,C, and D are equivalent expressions. Choice B is the odd one out.
