Answer 1

Answer:

i think itis option a

Step-by-step explanation:

because the asking a union b

make me as brainlist

Answer 2

Given; A={x:x is a factor of 15), B = {x:xis a factor of 18)

To Find; AB

Solution; factors of 15 are 1 , 3, 5, 15 do these are elements of A

Factors of X are 1, 3,6,9,18
