I'll absolutely worship anyone who helps out, I've got a trip scheduled soon, during the ongoing year, so I have to grind through my classes as quickly as possible. But in my Algebra class I found a sneaky little, fairly long, note-taking assignment and I've got no time or willpower to do it. Any help would be great.
