Step-by-step explanation
We can first array the sets in order to match the terms:
X= {15, 22, 33, 44, 89, 165, 1025}
Y= {-5, 15, 33, 88, 99, 150, 160, 1025}
We can see that the common terms are {15,33,1025}, thus the third statement is true.
Now, we can check if the second statement is true or false.
If we put both sets together from smaller to greater and using just one common term, we get the following expression:
X U Y = {-5, 15, 22, 33, 44, 89, 99, 150, 160, 165, 1025}
In conclusion, the second statement is also true.
