a need help Dilations-He Said, She Said (12/10)

Answer:
We conclude that the original triangle ΔDEF is dilated by a scale factor of 5/2 to get the image triangle ΔD'E'F'.
Therefore, 'Cárl' is correct. Hence, option 'a' is correct.
Step-by-step explanation:
Checking the location of the vertices of the original triangle ΔDEF
Checking the location of the dilated vertices of the image triangle ΔD'E'F'
Notice that if we multiply the vertices of the original triangle ΔDEF by 5/2, we get the correct image vertices of image triangleΔD'E'F'
i.e.
D(-2, 4) → D'(5/2 (-2), 5/2 (4)) → D'(-5, 10)
E(2, 4) → E'(5/2 (2), 5/2(4)) → D'(5, 10)
F(0, 2) → E'(5/2 (0), 5/2(2)) → F'(0, 5)
Thus, we conclude that the original triangle ΔDEF is dilated by a scale factor of 5/2 to get the image triangle ΔD'E'F'.
Therefore, 'Cárl' is correct. Hence, option 'a' is correct.
