The answer is C. the reson is because a function have to have a input that have only one output.
Pretty sure it's B because 50 isn't divisible by any of the other choices
Notice that 8 can be written in exponential form of 
When you see 
, recognize that 
3 × 
= 8
Hence, the answer is 
. Which means 256.
Here is some indices rules/formulas you might find helpful as well:
(4a + 6b) x (2a - 2b)
the answer would be 8a2 + 4ab - 12b2
I cannot see the entire problem, but based on what I can see, vertical angles are involved. Just know that vertical angles are always equal. An example would be that 1 and 3 are vertical.
Looking at the problem, the sum of angle 1 and angle 3 is 314. Since angle 1 and angle 3 are equal, angle 1 and angle 3 are both equal to 157. If the question is asking you to solve for angle 4 or 2, then you would use supplementary angles. 180-157 is 23, so the measure or angles 2 and 4 is 23. If the question if something other than what I mentioned, let me know and I will answer that, but I hope what I have helped!
