Answer:
CU = 12
Step-by-step explanation:
Clearly from the diagram of the triangle we can say that,
AD, BE and CF are the medians of the triangle ABC , since they are bisecting the sides of the triangle equally.
Also , U is the intersection point of the these mediands of the triangle whic is known as centroid of the triangle.
Now, from the property of the centroid , centroid divides the median in the ratio of 2 :1 from the point C .
Thus CU will be 
times of CF (median) .
Given is Cf equals 18 ,
Thus , CU = ×18 = 12.
So, CU equals 12 .
Answer:
n=23
Step-by-step explanation:
4-23=19

divide each by 5
3:4
to find the ratio of the area's we square the ratio's of the sides
3^3 : 4^2

The lines are intersected at point (0, -5). So (0, -5) is the solution.
Answer is the third one
(0,-5 )
