Question

1) a (x-y+(x-y);3) a (x+y)-(x+y);2) a (x+y)+63(x+y);4) x(a? +262) + y (a? +262).​

Answer 1

Ответ:

1) 2ax-2ay

2) ax+ay-x-y

3) ax+ay+63x+63y

4) ax+ay+262x+262y

Объяснение:

1) a(x-y+(x-y)=a(x-y+x-y)=a(x+x-y-y)=a(2x-2y)=2ax-2ay

2) a(x+y)-(x+y)=a(x+y)-x-y=ax+ay-x-y

3) a(x+y)+63(x+y)=ax+ay+63(x+y)=ax+ay+63x+63y

4) x(a+262) + y (a+262)=ax+262x+y(a+262)=ax+ay+262x+262y

Answer 2

It appears that you have provided a series of mathematical expressions with some missing information or placeholders marked as "(a?)" and "(x-y)", "(x+y)", etc. It's not entirely clear what you're asking or what you want to do with these expressions.

If you could provide more context or clarify your question, I'd be happy to help you with the mathematical expressions. Please specify what you want to do with these expressions or provide more details about what you're trying to achieve.
