Answer:
is this a math problem?
Step-by-step explanation:
True because u can always add or multiply to join groups
1st question: intersection is the numbers included in both sets
neither set shares any numbers so answer would be null set
2nd question: 2 numbers are in all 3 sets: (-2,9)
You don't have to look very far in either case. Both answers are "a".
1. Checking selection "a",
265 =? 35 +20*7 = 35 +140 = 175
a (7, 265) is NOT a solution
2. Checking selection "a",
18 =? 5*4 -2 = 20 -2 = 18
a (4, 18) IS a solution
