ex) I'm 21. Lower limit is 20 years old and upper is 23.

Curious what other people's margins are.

(sorry for poor grammar). My bf and I (21 and 22 respectively) have been together for almost two years since we began dating in college. Earlier today, he attended a drag show event with his work friends while I stayed home to relax. He came back 3 hours and told me all about it. At some point, he mentioned a drag queen (male) sat on his lap, wrapped his legs around my bf, and squeezed his pecs. At the end of the show, he took a photo with this drag queen arching against my bf's groin region, and he followed her on ig. I expressed to my bf that I didn't think this was okay, and that this crossed a line in our relationship. He acknowledged my main concern, but ultimately brushed off my feelings saying "Drag shows are supposed to be for good times." Am I crazy? I now feel like a awful jealous bf. Any recommendations on how I should handle this?

I'm taking Linear Algebra for the first time and I'm not sure how to solve this problem. Could anyone kindly explain how they determined the correct answers?
