Dude, come on.

Do your own freakin homework.

This is riduculous. If you are a student, that is your career, and you are responsible for being a student and doing your work. You need to leasrn this material for yourself to become a more knowledgeable person.

These are not hard questions at all.

Use that textbook you were issued at the beginning of the school year. It wasnt given to you sp it could collect dust.
