Perimeter is the sum of all three sides.
\n" ); document.write( "Let's call the missing side x. Then we can write
\n" ); document.write( "x + 5m-7 + 2m+5 = 24m-6
\n" ); document.write( "x + 7m-2 = 24m-6
\n" ); document.write( "Now subtract 7m and add 2...we get
\n" ); document.write( "x - 2 = 17m-6
\n" ); document.write( "x = 17m-4
\n" ); document.write( "the third side...
\n" ); document.write( "
