\"The perimeter of a rectangle is 28cm the length of the rectangle is 6cm more than its width. What is the length of the rectangle?\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = width
\n" ); document.write( "x + 6 = length\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Perimeter of a rectangle is 2(width) + 2(length)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x + 2(x + 6) = 28 {perimeter = 2(width) + 2(length)}
\n" ); document.write( "2x + 2x + 12 = 28 {used distributive property}
\n" ); document.write( "4x + 12 = 28 {combined like terms}
\n" ); document.write( "4x = 16 {subtracted 12 from both sides}
\n" ); document.write( "x = 4 {divided both sides by 4}
\n" ); document.write( "x + 6 = 10 {substituted 4, in for x, into x + 6}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "length is 10 cm
