I need this as soon as possible!! I will pay more if you can do this before 3:30pm EST today.
Please answer and explain all of the questions on this practice test. My professor gave us the solutions but I can hardly read his handwriting and I need more explanation. I especially need help with #2 and #4.
I’ve uploaded his solutions as well so you can use them as a guide (his handwriting sucks so I have a hard time reading them) to try help me understand what he is asking for.
Thanks!!
