Answer 1

Answer:

true because here : r=q & r=p...so, it's true

Step-by-step explanation:

please mark me as a brainlest please

Answer 2

Answer:

False because

Step by step explanation

<---•Q(-5)------•P(3)-------•R(6)--->

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

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

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

According to the problem given ,

LHS =D(P,R) + D(R,Q)

= 3 + 11 = 14

RHS = D( P , Q ) = 8

LHS ≠ RHS

Therefore ,

Given statement is False.

hope it works pls follow me and mark me brainlist pls I'll follow you back
