we know that

<u>The centroid</u> of a triangle is the intersection of the three medians of the triangle. The coordinates of the centroid are also two-thirds of the way from each vertex along that segment

so

in this problem

The point G is the centroid of the triangle ABC

AG=2GE ------> equation A

we have

AG=16\ GE=2x

substitute in the equation A and solve for x

16=2*(2x)

16=4x

x=4

BG=2GF ------> equation B

we have

BG=8x

substitute in the equation B and solve for GF

8x=2GF

GF=4x

substitute the value of x

GF=4*4=16

therefore

<u>the answer is</u>

She used GF=2BG, but the correct statement is BG=2GF
