\n" ); document.write( "===================
\n" ); document.write( "r = 7 since it's tangent to the x-axis.
\n" ); document.write( "--> $\"%28x-5%29%5E2+%2B+%28y-7%29%5E2+=+49\"$
\n" ); document.write( " $\"x%5E2+-+10x+%2B+25+%2B+y%5E2+-+14y+%2B+49+=+49\"$
\n" ); document.write( " $\"x%5E2+%2B+y%5E2+-+10x+-+14y+%2B+25+=+0\"$
\n" ); document.write( "-----------------
