Answer 2

It seems like you've provided three mathematical expressions. If you have specific questions or if you'd like me to simplify or evaluate these expressions, please let me know. Here's how these expressions look:

1. $a(m+n) - b(m+n)$
2. $x(2a-5b) + y(2a-5b)$
3. $2m(a-b) + 3n(b-a)$

If you need any specific calculations or further information about these expressions, please provide more details.
