This expression is a perfect square trinomial. It has two answers but they don't have to be different. In this case it has to be the same - because it is a perfect square trinomial.
60 seconds = 1 minute
60/15 = 4
12 hops in 15 seconds is the same as
4 * 12 hops in 4 * 15 seconds, or
48 hops in 60 seconds, and since 60 sec = 1 min, it equals
48 hops per minute.
P(head) = 1/2 = 50%
P(tail) = 1/2 = 50%
Answer:
add 17 to both sides
