Help for problems

[HallsofIvy]

Frankly, You are doing just about everything wrong! You chose to post a picture rather than type the question so basically you are asking other to do the work for you! Posting a photo, taken without sufficient light (and basically that would require a flood light!) so the white paper looks gray, making the handwriting harder to read and turned on its side! Further you have shown no attempt to do the problems yourself!
