I can't see 66 :( .

OpenStudy (jennychan12):

my work part 1. #67.

OpenStudy (jennychan12):

i just need 67-69

OpenStudy (jennychan12):

69 is still uploading. answer to 67 is 272 but i got 928....

OpenStudy (jennychan12):

#68. it's #67-69. I don't understand the reason for #69, but I know the answer. I know #67 is wrong, but I don't know why, and #68 is the same concept, so I don't know if I did that right either. Thank you!
