Answer:

Step-by-step explanation:
The equations are:


The two graphs intersect when:



To find the area under the curve for the first equation:

To find the area under the curve for the second equation:

To find the total area:

Simplifying the equation:

Note: The reason the area is equal to the area two minus area one is that the line, area 2, is above the region of interest (see image).
For the first 1 X= 11 because all you need to do is add or subtract the numbers visible.
The second would be 2.
None of them will get into a negative number. When you have like "2x" is the number twice, right? Some number has to be negative
