Consider the following expression: 4+(−6)⋅2/−(−3)^2. What is the simplified denominator?

To simplify the denominator of the expression \( 4 + (-6) \cdot 2 / -(-3)^2 \), we first focus on the expression within the denominator, which is:

\[
-(-3)^2
\]

First, we calculate \( (-3)^2 \):

\[
(-3)^2 = 9
\]

Next, we apply the negative sign in front of it:

\[
-(-3)^2 = -9
\]

Thus, the denominator simplifies to \(-9\).

Therefore, the simplified denominator is \(-9\).
