To simplify the expression 9/4x + 4 + 2x, we need to combine like terms.

The like terms in this expression are the two terms that involve x: 9/4x and 2x.

Adding these two terms together gives us: (9/4)x + 2x = (9/4 + 8/4)x = (17/4)x.

So the simplified expression becomes: (17/4)x + 4.

Therefore, the correct answer is D. 11/3x + 4.
