What is GC? A.9 B.12 C.13 D.14

D

Step-by-step explanation:

For the median GC, the distance from the vertex to the centroid G is twice as long as the distance from the centroid to the midpoint, that is

GC = 2 GD = 2 × 7 = 14 → D

robert puts 2 in each row

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
