Let x = distance from wall
\n" ); document.write( "then
\n" ); document.write( "x+8 = length of the ladder
\n" ); document.write( ".
\n" ); document.write( "(x+8)^2=x^2+12^2
\n" ); document.write( "(x+8)^2=x^2+144
\n" ); document.write( "(x+8)(x+8) = x^2+144
\n" ); document.write( "x^2+16x+64 = x^2+144
\n" ); document.write( "16x+64 = 144
\n" ); document.write( "16x = 80
\n" ); document.write( "x = 5 feet
\n" ); document.write( ".
\n" ); document.write( "But, remember, x is the distance from the wall
\n" ); document.write( "the length of the ladder is:
\n" ); document.write( "x+8 = 5+8 = 13 feet\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
