Answer:
(a-b)^3 = a^3 - 3a^2b + 3ab^2 - b^3.
Answer:
This problem is acually really simple.
Step-by-step explanation:
all you have to do is replace the a with a 3. SO It would look like this:
g(x)=3f(x)
hope this helps :)

89
Answer:
32
Step-by-step explanation:
32 X 2 = 64. 64 - 9 = 55.
Answer:
The three consecutive integers are:
8, 9, 10
Step-by-step explanation:
Given:
There are three consecutive integers.
Three times the smallest is 14 more than the largest.
To find the three integers.
Solution:
Since the integers are consecutive , so each have a common difference of 1.
For example : -3,-2,-1
Let the integers be = ![x,(x+1),(x+2)](https://tex.z-dn.net/?f=x%2C%28x%2B1%29%2C%28x%2B2%29)
Three times the smallest is 14 more than the largest can be given as:
![3x=(x+2)+14](https://tex.z-dn.net/?f=3x%3D%28x%2B2%29%2B14)
Simplifying and solving for
.
![3x=x+2+14](https://tex.z-dn.net/?f=3x%3Dx%2B2%2B14)
![3x=x+16](https://tex.z-dn.net/?f=3x%3Dx%2B16)
Subtracting both sides by ![x](https://tex.z-dn.net/?f=x)
![3x-x=x-x+16](https://tex.z-dn.net/?f=3x-x%3Dx-x%2B16)
![2x=16](https://tex.z-dn.net/?f=2x%3D16)
Dividing both sides by 2.
![\frac{2x}{2}=\frac{16}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B16%7D%7B2%7D)
∴ ![x=8](https://tex.z-dn.net/?f=x%3D8)
Smallest integer = 8
Next integer = 9
Largest integer = 10
