Matthew is attending a very loud concert. To avoid permanent ear damage, he decides to move farther away from the stage. Sound intensity is given by the formula I= k/d^2, where k is a constant and d is the distance in metres from the listener to the source of the sound. Determine an expression for the decrease in sound intensity if Matthew moves x metres farther away from the stage.
