A coefficient is a number multiplied by a variable.
In this case, our variable is a.
The coefficient is 12.
(PS: The +5 that isn't being multiplied by a variable is called a constant)
Answer:

Step-by-step explanation:
In every rhombus, when you have two diagonal segment bisectors, you will always have a circumcentre showing all midpoints of both segment bisectors, plus, it measures 90° all around, so with that being said, you have your answer.

First, we are going to find the scaling factor of the volume, and then, we are going to multiply that scaling factor by the volume of the smaller prism.
We know that our hexagonal prism <span>has dimensions that are triple the dimensions of a similar smaller hexagonal prism. The scaling factor for each dimension is 3, but since we have 3 dimension (a prism is a 3 dimensional figure), we need to rise that scaling factor to the power 3 (that represent the three dimensions of our prism):
</span>

<span>
Now we just need to multiply our volume scaling factor by the volume of our smaller prism:
</span>


<span>
We can conclude that the correct answer is the fourth choice: </span><span>

Answer:
6x^2 - 7x + 2.
Step-by-step explanation:
Use long multiplication:
6x^2 - 7x + 2 <--------------Answer.
