Distribute minus, 9, left parenthesis, x, plus, 1, right parenthesis, .−9(x+1).

To distribute the \(-9\) over the expression \( (x + 1) \), apply the distributive property. This involves multiplying \(-9\) by each term inside the parentheses:

\[
-9(x + 1) = -9 \cdot x + (-9) \cdot 1
\]

Now, simplify:

\[
-9(x + 1) = -9x - 9
\]

Thus, the expression simplifies to:

\[
-9x - 9
\]
