I'm in dire need of help, nothing I can find online helps, and I've been able to get Number 1 & 3 done. I just really need the answers so I can learn the process of how to get the right answers from now on, my teacher gave us notes to study, but they weren't correct apparently and he won't help us. I really just want to be able to learn from this so I can pass my class. Any help is really appreciated​
