Answer:
1. Describe set A.
A = {5, 10, 15, 20, 25, 30, 35}
(not sure if 35 or 55 coz it's blurry)
2. Describe set B.
B = {10, 20, 30, 40, 50, 60, 70}
3. What is A U B
A U B = {5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70}
4. What is A "interesting" B
A "intersect" B = {10, 20, 30}
5. What is the cardinality of:
A? A=7
B? B=7
A U B? A U B = 11
