Question: 1 / 400

If x=3, y=-4, and z=2, what is the value of xyz-4z?

-22

-30

To find the value of the expression xyz - 4z when x = 3, y = -4, and z = 2, we first need to calculate the product of x, y, and z.

Calculating xyz:

xyz = 3 * (-4) * 2

First, calculate 3 * (-4):

3 * (-4) = -12

Next, multiply this result by 2:

-12 * 2 = -24

Now, we need to calculate 4z:

4z = 4 * 2 = 8

Now we can substitute these values back into the original expression:

xyz - 4z = -24 - 8

Now, subtract 8 from -24:

-24 - 8 = -32

This indicates there might be an error in the response, as the calculation leads us to a different result. The correct value of xyz - 4z is -32. The available options do not include -32, suggesting that a recalculation of the options or values may be necessary to find a match.
