Answer 1

Answer:

OK friend this is a property OK friend

Answer 2

Answer:

Hi ,

<----|Q( -5 )---------|P(3)-------|R(6)------>

D( P,Q ) = 3 - ( - 5 ) = 8

D( P, R ) = 6 - 3 = 3

D( Q , R ) = 6 - ( - 5 ) = 6 + 5 = 11

According to the problem given ,

LHS = D( P, Q ) - D( P,R ) = 8 - 3 = 5

RHS = D( Q , R ) = 11

LHS ≠ RHS

Therefore ,

The statement is False.

I hope this helps you
