\n" ); document.write( "Let the width be x; then the length is 6x-4.

\n" ); document.write( "The area (length times width) is 20 square inches:

\n" ); document.write( "\"x%286x-4%29+=+20\"
\n" ); document.write( "\"6x%5E2-4x+=+20\"
\n" ); document.write( "\"6x%5E2-4x-20+=+0\"
\n" ); document.write( "\"3x%5E2-2x-5+=+0\"
\n" ); document.write( "\"%283x-5%29%28x%2B1%29+=+0\"

\n" ); document.write( "\"x+=+5%2F3\" or \"x+=+-1\"

\n" ); document.write( "Obviously the negative solution makes no sense in the problem....

\n" ); document.write( "So x = 5/3; 6x-4 = 10-4 = 6; the area is 6(5/3) = 20.

\n" ); document.write( "ANSWER: The dimensions of the rectangle are 5/3 inches by 6 inches.

\n" ); document.write( "Convert the 5/3 to a decimal rounded to the nearest hundredth if you need to....
