The true statements after evaluating the expression based on principle of commutativity and associativity are :
A: x + y = y + x
B; (x × y) × z = x × (y × z)
D: (x + y) + z = x + (y + z)
We are given;
x = a + bi
y = c + di
z = f + gi
Now according to properties of algebra, we know that;
- Commutative property states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. For example; a + b = b + a
- The Associative property states that; a × ( b × c) = b × (a × c) = c × (b × a)
Looking at the options :
A) x + y = y + x ; This is true as it follows Commutative property of addition
B) (x × y) × z = x × (y × z) ; This is true as it follows the Associative property.
C) x - y = y - x ; this is false as it does not follow both properties.
D) (x + y) + z = x + (y + z) ; This is true as it follows the Commutative property.
E) (x – y) – z = x – (y – z) ; This is False as it does not follow any of the 2 properties.

Answer:
In almost all Christian sacred music, the subjects are taken from the Bilical old or new testiments; or from closely related apocryphal stories that have a Biblical basis or connection. Secular music is music that does not primarily have a religious subject, though it can mention the devine or holy. Sacred music has plainsongs and is used during mass. Secular music always has instruments, and sacred music focuses more on the words. Secular music is more upbeat and happy, unlike sacred music.
