A quadratic equation is written in the form
Looking at the second, third, and fourth options, we see that the highest powers are greater than two, which automatically disqualifies them from being quadratics (since the highest power in a quadratic is 2).
This makes the first option the correct choice since the expansion of the equation gives 
Answer:
C is the most suspicious set.
Step-by-step explanation:
We would expect that B wins 4/5 * 30 = 24 games.
In set A, B wins 23 games.
In B, B wins 24 games.
In C, B wins 15 games.
In D, B wins 25 games.
So result C is very suspicious.
The lowest number of strands usually seen is 7 ... one in the middle
and 6
surrounding it.
The next level up is 19, which is another layer of 12
strands on top
of the 7.
After that the number varies, but 37 and 49 are
common, then in
the 70 to 100 range (the number is no longer exact).
Even larger
numbers than that are typically found in very large
cables.
