A rhombus has equal measure all around.\r
\n" ); document.write( "\n" ); document.write( "This means we can equate the given expressions and solve for x as step one.\r
\n" ); document.write( "\n" ); document.write( "3x + 2 = x + 12\r
\n" ); document.write( "\n" ); document.write( "3x - x = -2 + 12\r
\n" ); document.write( "\n" ); document.write( "2x = 10\r
\n" ); document.write( "\n" ); document.write( "x = 10/2\r
\n" ); document.write( "\n" ); document.write( "x = 5\r
\n" ); document.write( "\n" ); document.write( "Now, side AB = side DC.\r
\n" ); document.write( "\n" ); document.write( "AB was given to be 3x + 2.\r
\n" ); document.write( "\n" ); document.write( "Let x = 5\r
\n" ); document.write( "\n" ); document.write( "AB = 3(5) + 2\r
\n" ); document.write( "\n" ); document.write( "AB = 15 + 2\r
\n" ); document.write( "\n" ); document.write( "AB = 17 inches\r
\n" ); document.write( "\n" ); document.write( "If AB = DC, then DC = 17 inches\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
