Simplify 17d - 33 + 9 (2d + 6) - 11.

To simplify the given expression, we'll first use the distributive property to simplify the expression inside the parentheses:

9(2d + 6) = 9 * 2d + 9 * 6 = 18d + 54

Now we can rearrange the expression:

17d - 33 + 18d + 54 - 11

Combining like terms, we find:

(17d + 18d) - 33 + 54 - 11

Which simplifies further to:

35d + 10
