simplify the expression using the Distributive Property

To simplify the expression \( 4(9n - 3) \) using the Distributive Property, you multiply 4 by each term inside the parentheses.

1. Multiply \( 4 \) by \( 9n \):
\[
4 \times 9n = 36n
\]

2. Multiply \( 4 \) by \( -3 \):
\[
4 \times -3 = -12
\]

Now, combine the results:
\[
36n - 12
\]

So, the simplified expression is:
\[
\boxed{36n - 12}
\]
