One is a grandfather, one is a father, and the other is a son. Two fathers and two sons, but only 3 people since the father is both a dad and a son.
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.

The number of light bulbs that the firm will make in 9.36 × 10² weeks is 4.27 × 10^(6) bulbs.
<h3>What is Scientific notation?</h3>
This is known to be the method used to write a figure that very large or very small numbers.
Note that when the company makes a fixed quantity of light bulbs in a week, the amount of light bulbs can only be seen or found by multiplying that quantity by the number of weeks.
4.56 * 10^3 * 9.36 * 10^2
= 42.6816 * 10^5
= 4.26816 * 10^6.
Therefore, The company will produce 4.27 * 10^6 light bulbs in that time frame.
See full question below

Answer:
$50,000 for each year ie $100,000 for both years
Explanation:
She spends $25,000 on her worker for the year ans another $25,000($100 for each sq ft × 250sq fts) on land rent for one year, culminating to $50,000 per year. The cost is same for both year because there was no increment or decrement to her costs
