The perimeter of a triangle is found by adding the lengths of the three sides
\n" ); document.write( "The sum of three unknown consecutive integers can be expressed:
\n" ); document.write( "\"x%2B%28x%2B1%29%2B%28x%2B2%29+=+42\"
\n" ); document.write( "\"3x%2B3+=+42\" Subtract 3 from both sides.
\n" ); document.write( "\"3x+=+39\" Divide both sides by 3.
\n" ); document.write( "\"x+=+13\" and...
\n" ); document.write( "\"x%2B1+=+14\" and...
\n" ); document.write( "\"x%2B2+=+15\"
\n" ); document.write( "The lengths of the three sides are:
\n" ); document.write( "13 inches, 14 inches, and 15 inches.
\n" ); document.write( "
\n" );
