and
and
So this one is not prime, since you can still factor it.

and
and
So this one is not prime, since you can still factor it.

and
and
So this one is not prime, since you can still factor it.

and
and -x+2 cannot be further factored.
Therefore,
is a prime.
30 divided by 100 = 0.3 x 7.5 = 2.25 or 25%
