To simplify the expression \(-9(8x + 11)\), apply the distributive property by multiplying \(-9\) with each term inside the parentheses.

\[
-9(8x + 11) = (-9 \times 8x) + (-9 \times 11)
\]

Now, calculate:

\[
-9 \times 8x = -72x
\]
\[
-9 \times 11 = -99
\]

So, the simplified expression is:

\[
-72x - 99
\]
