Question : If $a=-12, b=-6$, and $c=18$, then what is the value of $\frac{2 a b c}{9}$?
Option 1: 554
Option 2: 288
Option 3: - 288
Option 4: 144
Correct Answer: 288
Solution :
Given $a=-12, b=-6$, and $c=18$
$\therefore$ $\frac{2 a b c}{9} = \frac{2\times(-12) \times (-6) \times 18}{9}$
$= 2\times 12\times 6\times 2 = 288$
Hence, the correct answer is 288.
