Your answer is correct!
\n" ); document.write( "The distance (d) between the points (2, 0) and (-5, 0) is found by:
\n" ); document.write( " $\"d+=+sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29\"$ here: $\"x%5B1%5D+=+2\"$ , $\"y%5B1%5D+=+0\"$ , $\"x%5B2%5D+=+-5\"$ , and $\"y%5B2%5D+=+0\"$ Making the appropriate substitutions, we get:
\n" ); document.write( " $\"d+=+sqrt%28%28-5-2%29%5E2%2B%280-0%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%28%28-7%29%5E2%29\"$
\n" ); document.write( " $\"d+=+sqrt%2849%29\"$
\n" ); document.write( " $\"d+=+7\"$ We discard the negative answer as distance is a positive value. \n" ); document.write( "

\n" );
