The correct answer choice is (B)
Answer:
The formula is:

Step-by-step explanation:
The geometric sequences are those in which the division between the terms
and
of the sequence are equal to a constant common reason called "r"
The geometrics secencias have the following form:

Where
is the first term of the sequence
In this sequence we have the following terms
1.2, 3, 7.5, 18.75
Then notice that:

Then:
and 
Finally the formula is:

Answer:
3/5
Step-by-step explanation:
Answer:
First Option is correct.
(x+2)(x+3)(x-4)
Step-by-step explanation:
Given:
The given factor is.

We need to find the factors of given factor.
Solution:

Substitute (-4x-10x) in the place of -14x

Rearrange the equation:

Now we factorised the above equation.
The factors of 
Now we substitute (x+2)(x-12) in the place of 
And in the place of 

Simplify 
![f(x)=x[(x+2)(x-2)]+(x+2)(x-12)](https://tex.z-dn.net/?f=f%28x%29%3Dx%5B%28x%2B2%29%28x-2%29%5D%2B%28x%2B2%29%28x-12%29)
Common factor for above function (x+2)
![f(x)=(x+2)[x(x-2)+(x-12)]](https://tex.z-dn.net/?f=f%28x%29%3D%28x%2B2%29%5Bx%28x-2%29%2B%28x-12%29%5D)
Simplify.
![f(x)=(x+2)[x^{2}-2x+x-12]](https://tex.z-dn.net/?f=f%28x%29%3D%28x%2B2%29%5Bx%5E%7B2%7D-2x%2Bx-12%5D)

The factor of 
So the factors of the function.

Therefore, the factors of the given function are (x+2)(x-4)(x+3)
