I have a study guide for a test. I understand pretty much everything, but I have a part which I'm not quite sure if I understood it or not. I learned it on monday but I haven't seen my teacher since due to her being sick today, no school wednesday, and i have her every other day. I have them done on a separate piece of paper but I want to check them. Can someone please help me?
