Final answer:
By substituting the values into the expression abc/3 with a = -6, b = -4, and c = 9, we find that abc = 216 and when divided by 3, abc/3 equals 72, which is option b.
Step-by-step explanation:
To find the value of abc/3, we substitute the given values of a, b, and c into the expression. Here, a = -6, b = -4, and c = 9. Multiplying these together:
- a * b * c = (-6) * (-4) * 9
- = 24 * 9
- = 216
Now divide by 3 to get the final value:
Therefore, the value of abc/3 is 72, which corresponds to option b.
