Question

Find pb, if pj=14 and jb= 28

Answer 1

pj=14

jb=28

p=14/j

b=28/j

pb=(14/j)×28/j

pb=392/j²

j²=9.333≅

pb=392/9.333

pb=42.0015≅42

Answer 2

42

Explanation:

Based on the information given, point j is the midpoint, as it is shared by both line segments. Set the equation:

pb = pj + jb

Note:

pj = 14

jb = 28

Plug in the corresponding numbers to the corresponding variables:

pb = pj + jb

pb = 14 + 28

pb = 42

pb = 42 is your answer.
