These are collected quiz questions I have gotten in my math class so far since the semester started. We would get the quiz back with only the grades but not the answers. And I've been having a very hard time getting these right. However, I been studying and learning before I answered them now. I would so appreciate if you could help me with whatever you can to get these answers. It is my first time using the Expert tutor in CourseHero and as it says I only have three changes to submit questions I don't want to waste it.
