Question: 1 / 400

Given x=3, y=-4, and z=2, what is the value of x(y-3z)?

-24

-30

To find the value of the expression $ x(y - 3z) $ using the given values $ x = 3 $, $ y = -4 $, and $ z = 2 $, we first need to calculate $ y - 3z $.

1. Start with $ z $:

- Since $ z = 2 $, we calculate $ 3z $:

\[ 3z = 3 \times 2 = 6 \]

2. Now substitute this back into the expression for $ y - 3z $:

- We already have $ y = -4 $:

\[ y - 3z = -4 - 6 \]

\[ y - 3z = -10 \]

3. Now that we have $ y - 3z = -10 $, we multiply this by $ x $:

- We substitute $ x = 3 $:

\[ x(y - 3z) = 3 \times -10 = -30 \]

Therefore, the correct value of the expression $ x(y - 3z) $ is $ -30 $, which means the choice is indeed consistent with this
