3. If D is the centroid of PQR, PA = 17 , BD = 9, and DQ = 14 , find each missing measure .

 a) AR =  17

               b) PR  = 34

               c) DR = 18

               d) BR = 27

               e) AD  = 7

               f) AQ = 21

Step-by-step explanation:

a) AR =  PA = 17

b) PR  = 2 · PA = 2 · 17 = 34

c) DR =  2 · BD = 2 · 9 = 18

d) BR = BD + DR = 9 + 18 = 27

e) AD  = (1/2) · DQ = (1/2) · 14 = 7

f) AQ =  AD + DQ = 7 + 14 = 21

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
