The universal set is the set of integers from 1 to 10. Then sets P, Q
and R are defined as : P = {p:p is a
even number} , Q = {q:q is a
Multiple of 3) and R = {r:ris a odd
number}. Write the sets P, Q and Rin
listing form and find PUQUR and P
nQn R.

See below in bold.

Step-by-step explanation:

P = {2, 4, 6, 8, 10}

Q = {3, 6, 9}

R = {1, 3, 5, 7, 9}

PUQUR is the union of the 3 sets and is:

{1, 2, 3,4, 5, 6, 7, 8, 9, 10}

P∩Q∩R is the intersection of the 3 sets and is:

∅.

- that is the empty set . There are no common elements in the 3 sets.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
