\n" ); document.write( "If the 8ft telephone pole casts a four foot shadow, a 14 ft giraffe casts an Xft long one. Set up a proportion of height to shadow:
\n" ); document.write( " $\"telephone%2Fshadow+=+giraffe%2Fshadow\"$ because the ratio is the same.
\n" ); document.write( "Next, substitute known values:
\n" ); document.write( " $\"8%2F4=14%2Fx\"$
\n" ); document.write( "Multiply both sides by 4X, also known as cross-cancelling
\n" ); document.write( " $\"8x=14%2A4\"$
\n" ); document.write( "Multiply 14 by 4
\n" ); document.write( " $\"8x=56\"$
\n" ); document.write( "Divide both sides by 8
\n" ); document.write( " $\"x=7\"$
\n" ); document.write( "
\n" ); document.write( "The final answer is: The giraffe has a seven-foot shadow.
