Answer:
![[x - 1][x + 1][{x}^{2} + 4]](https://tex.z-dn.net/?f=%5Bx%20-%201%5D%5Bx%20%2B%201%5D%5B%7Bx%7D%5E%7B2%7D%20%2B%204%5D)
Step-by-step explanation:
Knowing that you have to find two numbers that when they differ to 3, they also multiply to −4, and those numbers are −1 and 4. So, after clearing that up, you will have this [since our degree of this polynomial function is 4]:
![[{x}^{2} - 1][{x}^{2} + 4]](https://tex.z-dn.net/?f=%5B%7Bx%7D%5E%7B2%7D%20-%201%5D%5B%7Bx%7D%5E%7B2%7D%20%2B%204%5D)
Then, since
is factorable, you will get this:
![[x - 1][x + 1]](https://tex.z-dn.net/?f=%5Bx%20-%201%5D%5Bx%20%2B%201%5D)
Finally, attach
to the partially factored polynomial to get this:
![[x - 1][x + 1][{x}^{2} + 4]](https://tex.z-dn.net/?f=%5Bx%20-%201%5D%5Bx%20%2B%201%5D%5B%7Bx%7D%5E%7B2%7D%20%2B%204%5D)

Answer:
45
Step-by-step explanation:

add 6 on both sides to eliminate it(doing this will get us closer to the variable)
x/3=15
multiply both sides by 3
x=45
hope this helps!
Answer:
D
Step-by-step explanation:
if you look at the graph you can see that if you add 2 each tie to a problem it will not go left but right because right means the value is going up and left means the value is going down
Answer:
(a)
Step-by-step explanation:
Given
See attachment for sets A and B
Required
The true statement about both sets
First, we calculate the typical values (mean) of set A and set B.
This is calculated as:

For A:



For B:



<em>Here, we can conclude that B has a larger typical value</em>
Next calculate the spread (range) of sets A and B
This is calculated as:

For A:


For B


<em>Here, we can conclude that A has a larger spread.</em>
<em></em>
<em>Hence, (a) is true</em>
