Respuesta :

First we convert the tiles to expressions. Similar tiles can be summed up and written as one term. For example 2 tiles of x can be written as 2x.

So we are to add [tex] x^{2} +x[/tex] to [tex]2x+3[/tex].

The summation will be:

[tex] x^{2} +x+2x+3 \\ \\ = x^{2} +3x+3[/tex]

Therefore, option B is the correct answer.
