You can put this solution on YOUR website!
Cartesian distance = d = sqrt( dx^2 + dy^2 )
\n" ); document.write( "---
\n" ); document.write( "dx = -a - 2a
\n" ); document.write( "dx = -3a
\n" ); document.write( "---
\n" ); document.write( "dy = b - 4b
\n" ); document.write( "dy = -3b
\n" ); document.write( "---
\n" ); document.write( "d = sqrt( (-3a * -3a) + (-3b * -3b) )
\n" ); document.write( "---
\n" ); document.write( "d = sqrt( 9aa + 9bb )
\n" ); document.write( "d = sqrt( 9(aa + bb) )
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "d = 3 * sqrt( aa + bb )
