Maybe you don't understand what the question is - nor do we - is this verbatim and from where?

Maybe all they want is d[NO₂]/dt = - d[NO]/dt = -½ d[O₂]/dt = 4.0 X 10^-3

which you did not write because it was too obvious?

I would argue even just $r=4.0 \times 10^{-3} \frac {mol}{L \times s}$ qualifies as a correct answer

Yes but sometimes it is just as well to show off a bit.
