You can put this solution on YOUR website!
First of all, AD=BC, so BC also is 2x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Secondly, AB=CD, so 3x=2y+2. If you solve for 2y, 2y=3x-2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thirdly, Perimeter = Sum of four sides
\n" ); document.write( "2x+3x+2x+2y+2 = 40\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Simplify:
\n" ); document.write( "7x+2y+2=40\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute 2y=3x+2:
\n" ); document.write( "7x + 3x-2+2=40
\n" ); document.write( "10x=40
\n" ); document.write( "x=4 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2y=3x-2
\n" ); document.write( "2y=3*4-2
\n" ); document.write( "2y=10
\n" ); document.write( "y=5\r
