can someone help ?
No math tutor will touch this until you indicate what YOU think the answers are. It would also be a good idea to indicate WHY you think so for each one.
This looks like a test. I sure hope you're not trying to cheat!
im not i just really need help i don't understand it
If you don't understand any of it, then you need to let your teacher know. Apparently, you need to start over ... or maybe re-take the class just before this one.
