You would set your equation up like this:
f(x)*g(x)
(3x^2)*(x+2) or 3x^2(x+2)
3x^3+6x^2
Your answer would be C
Answer:
72 weeks
Step-by-step explanation:
If 1 week =$10.75 then $774 will be equal to $774×1 week=774 then divide by $10.75=72 weeks
Answer:

Step-by-step explanation:
Because the volume of a rectangular prism is 
, where l is length, w is width, and h is height, then 
. Dividing both sides by 4, we have 
. Dividing both sides by 4 again, we have 
. Now, dividing both sides by 11, we have 
Answer:

Step-by-step explanation:
First we have to multiply 7 by 17 (7x17).
Then you have to divide it by 2.
1/2 X base x height
Answer:
Step-by-step explanation:
In an arithmetic sequence, we keep adding/subtracting to get the next term in the sequence.
Therefore, we can make an equation that looks like this:
5k-(2k+1) = 7k+2-5k
We can subtract 2k+1 from 5k, and 5k from 7k+2, because from subtracting the difference would be the same. (common difference of sequence is what we would find)
Now, we just need to simplify.
5k-2k-1 = 2k+2
3k-1=2k+2
Now let's combine like terms, and we get:
k=3
Hope this helped!
