The second option would be parallel
Answer:
3² or 9
Step-by-step explanation:
Step 1: Add exponents

Step 2: Subtract exponents
You should get 3² because of exponent rules. Remember when you multiply exponents you add the powers and when you divide exponents you subtract the powers.
Answer: the second one
Step-by-step explanation:
The simplified ratio is 3:4
Option D- Commutative property of addition.
<u>Answer:
</u>
18 + 9 = 9 + 18 which illustrate commutative property of addition.
<u>Solution:
</u>
Step 1:
The given data is a commutative property of addition, because no-matter where we put the numbers, you will always get the same answer.
This can be represented by a + b = b+ a
Step 2:
From the given Data
18 + 9 = 9 + 18
When we add LHS and RHS we get the same answer 27.
Step 3:
If we exchange the numbers in this problem then also you will get the same answer.
9 + 18 = 18 + 9 which gives 27.
Result:
Hence we come to the conclusion; the given data illustrates commutative property of addition.
