Answer:
12
Step-by-step explanation:
When n teams play each other once, the total number of games is n(n-1)/2. Since each team played every other one 3 times, the relationship between number of teams (n) and number of games is ...
3(n(n-1)/2) = 198
n(n-1) = 132 = 12·11 . . . . . . multiply by 2/3 and factor
n = 12 . . . . . . n = -11 is also an extraneous solution to this quadratic equation
12 teams participated in this championship.
Answer:
None
Step-by-step explanation:
<em><u>Parallel </u></em>means exactly the same just lower or higher(same slope)
<u><em>Perpendicular </em></u>means they come together at a right angle, it is evident these do not
<em><u>Coincident </u></em>means directly on top of one another which they are not
Since it is none of these than the answer is obviously none of these ;)
