Question

Points P,Q,R are collinear such that d(p,q)=17, d(q,r)=8, find d(p,r)=?​

Answer 1

Answer:

9

Step-by-step explanation:

d(p q) =17

d(q r)=8 ( p r)=?

d(p q)-d(q r)=d(p r)

17 - 8 =9

d(p r) =9

Answer 2

Given : d(p,q)=17, d(q,r)=8, find d(p,r)=?

d(p,r) = d(p,q) + d(q,r) = 17+8 = 25

↑ d(p,r) = 25
