1 gallon is equal to 4 quarts.
So you can either get 2 quarts for $3, or 4 quarts for 3$
1 gallon is the better deal.
Check the forward differences of the sequence.
If 
, then let 
be the sequence of first-order differences of 
. That is, for n ≥ 1,
so that 
.
Let 
be the sequence of differences of ,
and we see that this is a constant sequence, 
. In other words, is an arithmetic sequence with common difference between terms of 2. That is,
and we can solve for 
in terms of 
:
and so on down to
We solve for 
in the same way.
Then
and so on down to
-2 + 4x - 4
= 4x-6
Make sure to distribute everything and then combine like terms.
Answer: 4x-6
The other factor is eight because 9 multiplied by eight is 72 and a negative times a positive is a negative
Answer:
It would be at a depth of 42 meters below the surface
Step-by-step explanation:
13(6)=78 -120+78=-42
