Chemical Kinetics Part 2

Given below are two statements :
Statement I : The rate law for the reaction A+B⟶C is rate (r)=k[A]2[B]. When the concentration of both A and B is doubled, the reaction rate is increased " x " times.
Statement II :The figure is showing "the variation in concentration against time plot" for a " y " order reaction.
The value off x+y is _______.
