Evaluate the expression for the given values of the variables. (Not sure)
3ab^2; a = -4, b = 2
A -48
B 96
C 48
D -96
Thank you!!
I almost went with C
The answer is A. -48.
3*(-4)*4 = -12 * 4 = ?
To evaluate the expression 3ab^2 with the given values a = -4 and b = 2, we substitute these values into the expression:
3ab^2 = 3(-4)(2^2)
First, we calculate the value of b^2:
b^2 = 2^2 = 4
Next, we substitute this value into the expression:
3ab^2 = 3(-4)(4)
Now, we perform the calculations:
-4 * 4 = -16
Finally, we multiply the result by 3:
3 * (-16) = -48
Therefore, the evaluation of the expression 3ab^2 when a = -4 and b = 2 is -48.
So, the correct answer is A. -48.
