Ответ:-3x+3y-6..........

Answer 3

Solution

To expand the expression -3(х-у+2), we can use the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.

So, we can expand the given expression as follows:

-3(х-у+2) = -3*х - (-3)*у + (-3)*2

Now, let's simplify each term:

-3*х = -3x -(-3)*у = 3y -3*2 = -6

Therefore, the expanded form of the expression -3(х-у+2) is -3x + 3y - 6.

Answer

The expanded form of the expression -3(х-у+2) is -3x + 3y - 6.
