Reposting again because this is the FOURTH time I've gotten incorrect answers for the same problem, please don't answer if you don't have correct answers! Using this service costs money and I only have a limited amount of questions per subscription; I've complained multiple times now to Chegg about the lack of correct answers and also spammers to get partial refunds but I can't keep doing this.

There are 4 blanks total. Even though I answered the first and last blank as correct,I don't know how to get the answer (I just found them online) so if you could show me the formulas and get the same answer again please show and dom'nt just answer the two incorrect blanks in the middle, PLEASE ANSWER ALL FOUR (4) BLANKS INCLUDING THE ONES I HAVE MARKED AS CORRECT SO I KNOW HOW TO DO THEM... Thank you
