\"the perimeter of a rectangle is 24. The length of the rectangle is eight less than three times the width. find the dimensions of the rectangle\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = width
\n" ); document.write( "3x - 8 = length {length is 8 less than three times width}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter of a rectangle = (2 x width) + (2 x length)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x + 2(3x - 8) = 24 {perimeter is (2 x width) + (2 x length)}
\n" ); document.write( "2x + 6x - 16 = 24 {used distributive property}
\n" ); document.write( "8x - 16 = 24 {combined like terms}
\n" ); document.write( "8x = 40 {added 16 to both sides}
\n" ); document.write( "x = 5 {divided both sides by 8}
\n" ); document.write( "3x - 8 = 7 {substituted 5, in for x, into 3x - 8}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "width = 5 and length = 7
