Question: 1 / 400

What is the value of the expression (y)(z) for y = -4 and z = -2?

8

To find the value of the expression \( (y)(z) \), we substitute the given values for \( y \) and \( z \). Here, \( y = -4 \) and \( z = -2 \).

Now, we multiply the two values:

\[

(y)(z) = (-4)(-2)

\]

When multiplying two negative numbers, the result is positive. Therefore:

\[

(-4)(-2) = 8

\]

This shows that the value of the expression \( (y)(z) \) is indeed 8. The understanding of the rule that multiplying negative numbers yields a positive product is key to arriving at the correct result.
