Answer:
2(r+4)(r-4)
Step-by-step explanation
First, you want to factor out 2 from both terms, which gives you 2(r^2-16). Then you want to recognize that (r^2-16) is factorable into 2 terms. If you multiply (r+4) by (r-4) then you are given (r^2-16) as a result.

Answer:
The last one of commutative property of addition since there is no swapping of numbers related with addition.
Answer:


Step-by-step explanation:
Given
Let x represent years and V represents the value.
So, we have:


Solving (a): The linear function
First, we calculate the slope (m)

This gives:



The linear function is calculated using:

Where:


So, we have:

Open bracket


Make v the subject


So, the function is:

Solving (b): When x = 8
Substitute 8 for x in 



Take LCM




<em>Hence, its value after 8 years is 1313.3</em>
Answer: X ≤ 6
