Question

Evaluate -3 a parentheses 2b minus 4C parentheses a equals negative 3 B equals two and C equals -7

Answer 1

Answer:

288

Step-by-step explanation:

We want to evaluate the expression:

$- 3a(2b - 4c)$

For

$a = - 3 \\ b = 2 \\ c = - 7$

We substitute the given values into the expression to get:

$- 3( - 3)(2 \times 2 - 4 \times - 7)$

This gives us:

$9(4 + 28)$

Evaluate the parenthesis:

$9(32)$

$= 288$
