#6 - "Evaluate the definite integrals." Help please!

Thanks but I am not understanding the integral. Could you please write it out. I am not understanding what you have typed.    For example A=∫35∫0x-3dydx+∫5k∫01x-4+1dydx    =∫35x-3dx+∫5k1x-4+1dx    =x22-3x35+lnx-4+x5k   =252-15-92+9+lnk-4+k-ln5-4-5   =8+9-15-5+k+lnk-4   =k-3++lnk-4   Is this the integral of 35 integral 0x-3 dydx
