You can put this solution on YOUR website!
\"x=perimeter-22\"= length of the longer side,
\n" ); document.write( "so \"x%2B22=perimeter\"
\n" ); document.write( "
\n" ); document.write( "Since consecutive even integers are 2 units apart,
\n" ); document.write( "\"x-2\"= length of the medium-length side
\n" ); document.write( "\"x-4\"= length of the shortest side
\n" ); document.write( "
\n" ); document.write( "The perimeter is the sum of the side lengths, so
\n" ); document.write( "\"x%2B%28x-2%29%2B%28x-4%29=x%2B22\"
\n" ); document.write( "That is our equation.
\n" ); document.write( "I will work on that equation in lots of baby steps,
\n" ); document.write( "just in case you want to see all those steps.
\n" ); document.write( "You probably want to use less steps,
\n" ); document.write( "and your teacher probably does not expect or want to see too many steps.
\n" ); document.write( "
\n" ); document.write( "\"x%2B%28x-2%29%2B%28x-4%29=x%2B22\"
\n" ); document.write( "\"x%2Bx-2%2Bx-4=x%2B22\"
\n" ); document.write( "\"x%2Bx%2Bx-2-4=x%2B22\"
\n" ); document.write( "Adding \"6\" to both sides of the equal sign, we get
\n" ); document.write( "\"x%2Bx%2Bx-2-4%2B6=x%2B22%2B6\"
\n" ); document.write( "\"x%2Bx%2Bx%2B6-2-4=x%2B28\"
\n" ); document.write( "\"%28x%2Bx%2Bx%29%2B%286-2-4%29=x%2B28\"
\n" ); document.write( "\"3x%2B0=x%2B28\"
\n" ); document.write( "\"3x=x%2B28\"
\n" ); document.write( "\"3x-x=x%2B28-x\"
\n" ); document.write( "\"3x-x=28%2Bx-x\"
\n" ); document.write( "\"2x=28%2B%28x-x%29\"
\n" ); document.write( "\"2x=28\"
\n" ); document.write( "\"2x%2F2=28%2F2\"
\n" ); document.write( "\"highlight%28x=14%29\"
