Ответ: - 2mn + 5n.

Answer 2

To expand the expression -n(2m - 5), you need to distribute the -n to each term inside the parentheses. This process is known as "distributive property" or "expanding the expression."

Let's apply the distributive property:

-n(2m - 5) = -n * 2m + (-n) * (-5)

Now, multiply each term by -n:

-2nm + 5n

So, the expanded form of -n(2m - 5) is -2nm + 5n.
