Manny says that the diagram shows a centroid. Is he correct? Why or why not?

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

i believe that the slope of the line is -5

step-by-step explanation:

x = 3 ± √(5+y)

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
