Given A = {a, e, i, o, u} and B = {a, l, g, e, b, r}, find A ∪ B.
kupik [55]
indicates you want the UNION of sets A and B. So just make a list of elements that are in either set ("put all the elements into one 'box'"). Elements are listed only once; example: a is in both sets, so put it in the union only once.
Answer: the 3rd choice, {a, b, e, g, i, l, o, r, u}

Answer:
The sum of the first five classroom numbers in a row is 5k + 20
Step-by-step explanation:
Since the smallest classroom number on the side of the building is numbered k and each consecutive odd integer is separated by a difference of
2.
Therefore:
k is the first class room.
k + 2 is the second class room.
k + 4 is the third class room.
k + 6 is the third class room.
k + 8 is the fifth class room.
The sum of the five consecutive class rooms are given as:
k + (k + 2) + (k + 4) + (k + 6) + (k + 8)
collecting alike terms we get
= k + k + k + k + k + 2 + 4 + 6 + 8
= 5k + 20
Therefore, The sum of the first five classroom numbers in a row is 5k + 20.
