$\"+-28=-4sqrt+%28r%2B8%29\"$
\n" ); document.write( "By looking at it, I see that $\"+sqrt%28+r+%2B+8+%29+\"$
\n" ); document.write( "must equal $\"+7+\"$
\n" ); document.write( "Then I have $\"+-28+=+-28+\"$
\n" ); document.write( " $\"+sqrt%28+r+%2B+8+%29+=+7+\"$
\n" ); document.write( "Square both sides
\n" ); document.write( " $\"+r+%2B+8+=+49+\"$
\n" ); document.write( " $\"+r+=+41+\"$ \n" ); document.write( "

\n" );
