Answer:
288
Step-by-step explanation:
We want to evaluate the expression:
[tex] - 3a(2b - 4c)[/tex]
For
[tex]a = - 3 \\ b = 2 \\ c = - 7[/tex]
We substitute the given values into the expression to get:
[tex] - 3( - 3)(2 \times 2 - 4 \times - 7)[/tex]
This gives us:
[tex]9(4 + 28)[/tex]
Evaluate the parenthesis:
[tex]9(32)[/tex]
[tex] = 288[/tex]
