Question 2
In rectangle $ABCD,$ $AB = 12$ and $BC = 10.$ Points $E$ and $F$ lie inside rectangle $ABCD$ so that $BE = 9,$ $DF = 8,$ $\overline{BE} \parallel \overline{DF},$ $\overline{EF} \parallel \overline{AB},$ and line $BE$ intersects segment $\overline{AD}.$ The length $EF$ can be expressed in the form $m\sqrt{n} - p,$ where $m,$ $n,$ and $p$ are positive integers and $n$ is not divisible by the square of any prime. Find $m + n + p.$
