The answer is 13.6
Step-by-step explanation:
13.6 in fraction form is
or 
Answer: The graph is attached.
Step-by-step explanation:
The region is limited by two lines:
and 
You can write the first inequlity
in the following form:

This region are all the values for which the y-axis is less than the line f(x)=x+6 (all the values under the line).
The other inequality x ≤ 4 are all the values for which the x-axis is less than the line x=4 (all the values to the left of the line).
Observe the graphs attached.
So, let's take a look! When doing volume, we always do (addition) and nothing else. The only time that we would have to multiply is if we would have to find the area, but in this case, we are (going to figure) out what would be the volume.
We would sum up the following:

.
I believe that we would multiply this by (2) because we would have to find the other side as well.
And this would give us . . . 64 as it's volume.
V= (64)
The answer will be Relational Expression as y and x are being compared, one being greater/smaller than the other.
