Current Source Dissipating Power or Providing Power?
You have done the numerical part of the calculation correctly.

The current sources sum to 4A, which gives a terminal voltage of 10v on the resistors. Therefore, taking into account the direction of current at each component, the power flow at each component is

5A - generating 50W
1A - generating 10W
2A - dissipating 20W
5ohms - dissipating 20W each

Whether the sign of the final answer is correct depends on what sign convention has been established for the question. 

the power absorbed to the rest of the circuit is garbled nonsense, so it's anybody's guess.
