Answer 2

It looks like you've provided some algebraic expressions, and it appears you want to simplify them. Let's simplify each expression step by step:

1. (-4ab - 5a')

To simplify this expression, you can't combine the terms further because 'a' and 'a'' (a prime) are different variables. So the simplified expression remains:

-4ab - 5a'

2. (-3b - 2ab)

Similarly, in this expression, 'b' and 'ab' are different variables, so you can't combine them further. The simplified expression is:

-3b - 2ab

3. (0,2х + 5xy)

I notice that there is a comma (,) instead of a period (.) between the 0 and 2 in this expression. Assuming you meant it as a decimal point, let's simplify it:

0.2x + 5xy

Now, the terms can't be combined further because they involve different variables.

4. (4xy + 0,5y)

Again, there seems to be a comma (,) instead of a period (.) between the 0 and 5 in this expression. Assuming you meant it as a decimal point, let's simplify it:

4xy + 0.5y

Now, you can't combine these terms further because they involve different variables.

Please ensure to use the correct punctuation when writing mathematical expressions to avoid confusion. If you have any specific algebraic manipulations you'd like to perform or if you have any other questions, feel free to ask.
