To simplify the expression \( 7(2x - 4) \) using the distributive property, you multiply each term inside the parentheses by 7.

Here's the calculation:

  1. Multiply \( 7 \) by \( 2x \): \[ 7 \cdot 2x = 14x \]

  2. Multiply \( 7 \) by \( -4 \): \[ 7 \cdot -4 = -28 \]

Now, combine the results:

\[ 7(2x - 4) = 14x - 28 \]

So, the simplified expression is: \[ 14x - 28 \]
