Answer:
d(P, Q) = 6
d(Q, R) = 5
Step-by-step explanation:
The formula of a distance between two points A(a) and B(b):
d = |b - a|
We have P(x + 3), Q(x- 3), R(x + 2).
Substitute:
d(P, Q) = |(x - 3) - (x + 3)| = |x - 3 - x - 3| = |-6| = 6
d(Q, R) = |(x + 2) - (x - 3)| = |x + 2 - x - (-3)| = |2 + 3| = |5| = 5
