the lengths of the sides of a quadrilateral are consecutive even integers. twice the length of the shortest side plus the length of the longest side is 120 inches. find the lengths of all four sides.
\n" ); document.write( ":
\n" ); document.write( "The sides: x, (x+2), (x+4), (x+6)
\n" ); document.write( ":
\n" ); document.write( "Write an equation for:
\n" ); document.write( "\"twice the length of the shortest side plus the length of the longest side is 120 inches.\"
\n" ); document.write( "2x + (x+6) = 120
\n" ); document.write( "3x + 6 = 120
\n" ); document.write( "3x = 120 - 6
\n" ); document.write( "3x = 114
\n" ); document.write( " x = 114/3
\n" ); document.write( " x = 38
\n" ); document.write( ":
\n" ); document.write( "The sides: 38, 40, 42, 44
