Wait, I got 3 Ep, this is since everyone takes a language. there is 6 more in chinese then spanish. so you do 47+6 to get 53 you then add 53 an 47 to get 100. Then you do 100-97 to get 3
Ask again if you still are confused
Also to solve it just remeber the pythagorean theorem, a^2+b^2=c^2 to solve this. FYI c is the hypotenuse
Wait isnt the longer leg the hypotenuse?
Well the first year it would be 1500 penguins but since they lost 20% you multiply 1500 by 0.2 to get 300. 1500-300 = 1200. Then if you repeat the steps you should be able to get the final answer. P.S. dont half 1000 half the number of penguins that you got previously.
Wait im kind of confused on how you went from this z^4(z^3 + 8) - 2i(z^3 + 8) = 0 to this (z^4 - 2i)(z^3 + 8) = 0. The answer is prob correct tho.
Hmm idk if its just me but the first equation cant be simplyfied and for the 2nd one i got it from x^2+y^2=56-2xy -> 2xy+x^2+y^2=56 ->xy+x^2+y^2=24. Now i dont think you can simplify it anymore so.....
