Hi, cle1991!

We do help people with homework on this site. But, the keyword here is "help". We don't directly answer homework questions for students here. If we did, how would that be helping them to learn how to come up with the answers themselves?

If you use this site to get help with your homework, please do take some time to come up with and post what you think might be the answers yourself. If you do that, it's likely that you'll have someone very knowledgeable about whatever subject who'll be willing to discuss with you how and why your answers are correct or incorrect.

Please also read the expectations concerning the posting of homework questions that can be found via clicking on the following link.
