The union of sets p = {5, 6, 7, 8, 9} q = {1, 2, 3, 4, 5} is given by which of the following? {1, 2, 3, 4, 5, 6, 7, 8, 9} {1, 2, 3, 4, 5, 5, 6, 7, 8, 9} ø {5}

First option.

Step-by-step explanation:

Given two sets A and B, the union (A∪B) will be the set of elements which belong to either A or to B or to both.

Inf this case you have these two sets:

{} and {}

To find the union of these sets, put together the elements of the set P and the elements of the set Q (you need  to remember that no element must be repeated).

Then, you get that the union of sets P and Q is:

∪{}

This matches with the first option.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
