The fact that the largest triangles are similar and that HF and LJ are medians, we know that triangle HFE and triangle LJI are congruent. Similarity allows us to set up proportions of congruent sides. (Write these fractions vertically and solve. 9/6 = (x + 2)/(2x - 4)
This is because when you take 1.625 it rounds back to 6 because 2 isnt more then 5 or 5 so it wouldn't round just like 1.635. I believe thats the answer im not positive
