Step-by-step explanation:
Perfect square trinomial is defined by the follow way
Now we can rewrite 
as 
because a squared add is equal to multiply the add by itself one time
if we make a=3x and b=-5 we can see tha the first answer is the only option that could be a perfect square triomial

Answer:
9 teams
Step-by-step explanation:
If the total games played was 36 and no team played each other twice, we need to ensure there isn't any double counting.
36 = (n-1) + (n-2) + (n-3) ... + (n-(n-1))
using this knowledge, we can then count up:
1+2+3+4+5+6+7+8 = 36
If our highest number is 8, then we know there must be 9 teams, because no team can play themselves.
