Question

-3(2z - 8d)
use z = 6 and d = 7

Answer 1

Answer:

132

Step-by-step explanation:

1. -3(2z-8d) Solve within the parenthesis.

2. 2(6)=12, 8(7)=56

3. Do the math within the parenthesis with our new integers. 12-56=-44

4. multiply both integers now. -3(-44) = 132

*a negative times a negative wil give you a positive answer.

Answer 2

Answer:

12

Step-by-step explanation:

If z = 6 and d = 7, we can fill them in the variables. Let's rewrite the expression:

-3([ 2 × 6 ] - [ 8 × 7])

Let's start with the stuff inside the brackets. 2 × 6 minus 8 × 7. We know 2 × 6 = 12, and 8 × 7 = 56.

Then we have -3( 12 - 56 )

We then have to do 12 - 56, which gets us -44.

We now have -3( -44 ) or -3 × (-44)

-3 × (-44) = 12

Thus, we get our final answer of 12.
