Question

Expand 4(3z−7)
.(1 point

1 answer

To expand the expression \( 4(3z - 7) \), you need to distribute the \( 4 \) to both terms inside the parentheses:

\[ 4(3z) - 4(7) \]

Calculating each term:

\[ 4 \cdot 3z = 12z \] \[ 4 \cdot 7 = 28 \]

Putting it all together, the expanded expression is:

\[ 12z - 28 \]

So, \( 4(3z - 7) = 12z - 28 \).
