Question

Evaluate each expression is A = -4, B = 6, and C = -9 2. a³+c²-3.B ?

a) -216

b) -438

c) -642

d) -750

Answer 1

To evaluate the expression a³+c²-3B, where a = -4, b = 6, and c = -9, substitute the values and simplify the expression to find the answer.

Step-by-step explanation:

To evaluate the expression a³+c²-3B, we substitute the given values for a, b, and c which are a = -4, b = 6, and c = -9:

a³ + c² - 3B = (-4)³ + (-9)² - 3(6)

Simplifying this expression, we have:

-64 + 81 - 18

Finally, evaluating the expression:

-1

Therefore, the correct option is (a) -216.
