solve: the perimeter of a certain rectangle is 16 times the width.
\n" ); document.write( " The length is 12 cm more than the width.
\n" ); document.write( " Find the width of the rectangle.
\n" ); document.write( ":
\n" ); document.write( "Let x = the width
\n" ); document.write( "then
\n" ); document.write( "(x+12) = the length
\n" ); document.write( "and
\n" ); document.write( "16x = the perimeter
\n" ); document.write( ":
\n" ); document.write( "the perimeter equation:
\n" ); document.write( "2(x+12) + 2x = 16x
\n" ); document.write( "2x + 24 + 2x = 16x
\n" ); document.write( "4x + 24 = 16x
\n" ); document.write( "24 = 16x - 4x
\n" ); document.write( "24 = 12x
\n" ); document.write( "x = \"24%2F12\"
\n" ); document.write( "x = 2 cm is the width
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution using the perimeter (14cm = the length
\n" ); document.write( "2(14) + 2(2) = 16(2)
\n" ); document.write( "28 + 4 = 32 \n" ); document.write( "
\n" );
