The length of a rectangle is 6 inches more than 4 times the width. If the area of the rectangle is 54 square inches, find the length and the width.
\n" ); document.write( "***
\n" ); document.write( "let x=width of rectangle
\n" ); document.write( "4x+6=length of rectangle
\n" ); document.write( "width*length=area
\n" ); document.write( "x(4x+6)=54
\n" ); document.write( "4x^2+6x=54
\n" ); document.write( "4x^2+6x-54=0
\n" ); document.write( "2x^2+3x-27=0
\n" ); document.write( "(2x+9)(x-3)=0
\n" ); document.write( "x=3
\n" ); document.write( "4x+6=18
\n" ); document.write( "width of rectangle=3 inches
\n" ); document.write( "length of rectangle=18 inches \n" ); document.write( "
\n" );
