I think what beenthere is saying is that you need to show us the work you have done.

 

In the second problem, the first opamp circuit is a Sallen-Key highpass filter and the second opamp circuit is a Sallen-Key lowpass filter. Depending on the relative values of the corner frequencies of the highpass and the lowpass, the overall frequency response could be a bandpass or a bandstop (notch) filter
