the perimeter of a triangle is 31 cm. sides #1 and #2 have epual length,
\n" ); document.write( " while side #3 is one centimeter shorter than twice the length of side #1.
\n" ); document.write( " how long is each side
\n" ); document.write( ":
\n" ); document.write( "Let x = side one
\n" ); document.write( "and x = side two
\n" ); document.write( ":
\n" ); document.write( "\"side #3 is one centimeter shorter than twice the length of side #1\"
\n" ); document.write( "therefore:
\n" ); document.write( "(2x-1) = side three
\n" ); document.write( ":
\n" ); document.write( "Perimeter:
\n" ); document.write( "x + x + (2x-1) = 31
\n" ); document.write( "You can do it now, I'm sure \n" ); document.write( "
\n" );
