If they aren't, please tell me what the correct ones are. I'm way behind schedule and would like to get this done.

Please show us briefly - how you chose those answers. We can then discuss how you could correct the wrong answers.
 
As our name implies, we are a help site rather than an answer site. It is true that we will often tell you if your answers are right or wrong. But it is not very helpful to know that your answer is wrong. We need to see your reasoning.to give meaningful help.

You aren't making it easy for us to read this, with all the scrolling we have to do. This is too many problems to show at once.

But how about telling us your reasoning at least for 5 and 8, and any others that you are specifically unsure of.
 
Tbh I just copied it off another site I saw hahaha
I read the lesson explanation and it made my head spin!! Just can't wrap my head around it.

So those aren't even your answers??

In order to help you understand any of this, we need to know what you do understand.

Do you know anything at all that might be relevant? Tell us!

Is there something specific that you have questions about? Ask them!
