Either of two angles whose sum is 180 degrees
Answer: 40%
Step-by-step explanation:
(x-12)(x-12) would factor to x²-24x+144.
(x-12)(x+12) = x²+144
Option C is correct :)
Answer: 
This is the same as writing 7*Ln( e^(2x) + 10) + C
=======================================================
Explanation:
Start with the equation 
Apply the derivative and multiply both sides by 7 like so

The "multiply both sides by 7" operation was done to turn the 2e^(2x) into 14e^(2x)
This way we can do the following substitutions:

Integrating leads to

Be sure to replace 'u' with e^(2x)+10 since it's likely your teacher wants a function in terms of x. Also, do not forget to have the plus C at the end. This is a common mistake many students forget to do.
To verify the answer, you can apply the derivative to it and you should get back to the original integrand of 
The midpoint formula is x1+x2 divided by 2 minus y1+y2divided by 2. You should get your midpoint as a coordinate in the form of (x , y)
