The property used in the equation \(-3(x+5) = -3x - 15\) is the **Distributive Property**.

The Distributive Property states that for any numbers \(a\), \(b\), and \(c\):

\[
a(b + c) = ab + ac
\]

In this case, we can apply it as follows:

\[
-3(x + 5) = -3 \cdot x + (-3) \cdot 5 = -3x - 15
\]

Thus, the equation is correctly applying the Distributive Property to expand the left side.
