Answer:
d. The triangles are not similar because 6/13 ≠ 8/20.
Step-by-step explanation:
△ABC is similar to △DEF ,If the length of their corresponding sides are proportional.
ie : 6/13 = 8/20 = 10/25
Since , 6÷13 = 0.461538461538 ≠ 0.4 = 8÷20
Then
6/13 ≠ 8/20
Therefore , the triangles are not similar.

Did you get the answer me and you need help and no one dont want to help i hope you found the answer because i really need it math is very hard.
1-(-18)= 19
sense the subtract and negative cancel out, look at it as a plus sign between 1 and 18 so 1+18=19
