Simplifying a circuit w/ multiple resistors & current source

[Cocoleia]

Homework Statement

I am given this circuit:
https://mail.google.com/mail/u/0/?ui=2&ik=ac16233c7c&view=fimg&th=157871927bfab85f&attid=0.3&disp=inline&safe=1&attbid=ANGjdJ_NBCzBtsxNBxpVBZxZYQhZBjV1KlRTvTIVWx8ywfyYGYgtKpez7JOOWa_t8GbsfP3Hp9ODP0iatO0VG1zN1WomVMiLbznnfU2kAs3svgcsod_Y94bTkZdEMYI&ats=1475440357233&rm=157871927bfab85f&zw&sz=w1366-h643

And told to simplify it to the maximum.

This is my final result. I was wondering 3 things:
1. Are the 20 and 10 resistors in series
2. Is the 20 resistor on top in parallel with the 20 and the 10
3. Are the 10 and 40 resistors in series[/B]
