Okay, I can't upload a picture (my phone is broken so I'll try to explain the answer for problem number 7. Here you go: top left box EE, top right box Ee, bottom left box Ee, bottom right box ee. Also, you know to add two capital E's on top of the two top boxes like in the example for problem number 9 it has two lowercase n's (I hope I explained that in a way you can understand). on the left side of the top and bottom boxes, you should have E (top) and e (bottom).
