Remember the perimeter is the sum of all sides of a triangle. So if the sides are 3x + 7, 4x - 9, and 5x + 6, simply add them all up to get\r

\n" ); document.write( "\n" ); document.write( "\"Perimeter=%283x+%2B+7%29%2B%284x+-+9%29%2B%285x+%2B+6%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Perimeter=%283x%2B4x%2B5x%29%2B%287-9%2B6%29\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Perimeter=12x%2B4\" Combine like terms\r
