Answer: If you do the math right, you should've gotten 2.5 as the scale factor. That statement is true. If you did the math incorrectly you should've gotten 0.4, but that is false. In simpler words: The first statement is wrong. The second statement is right.
Step-by-step explanation:
To find the scale factor, take the length of the larger shape and divide it by the smaller shape. In this question you'd be taking the triangle with the length of 5 and divide it by the triangle with the length of 2.
