Please help with this questions. I’ve waisted over 100 points trying to get answers for one assignment just because the only people answering are giving me links. I’m not gonna ask for no links because I learned from experience, it doesn’t work. Please just help me so I can finish. And if you put these links, your honestly a really mean person.
