Expand 4(3z - 7). (1 point)
12z - 28
To expand 4(3z - 7), you need to distribute the 4 to both terms inside the parentheses.
First, multiply 4 by 3z:
4 * 3z = 12z
Next, multiply 4 by -7:
4 * -7 = -28
So, the expanded form of 4(3z - 7) is 12z - 28.
To expand the expression 4(3z - 7), you will distribute the 4 to both terms inside the parentheses. This means you will multiply 4 by both 3z and -7. Here's the step-by-step process:
1. Multiply 4 by 3z: 4 * 3z = 12z
2. Multiply 4 by -7: 4 * -7 = -28
Therefore, the expansion of 4(3z - 7) is 12z - 28.
