How many terms are in the expression 3+y+2xy-xy squared

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
