I believe the answer to your question id d. 56
2x+5+(6x+1)
you distribute an invisible one to get them out of the parentheses
2x+5+6x+1
You then add like terms
8x+6

Answer:
Correct answer is the domain.
Step-by-step explanation:
A domain is the input set of a function.
A range is the output set of the function.
It is more important to know the domain of the function to be able to determine the corresponding output set so the function can be graphed. To start with the domain is very useful because every domain element has a corresponding unique output element.
Suppose you started with the range element of 9. The input set for an output of 9 is {-3,3}. This makes it hard to match up the elements. This example highlights why it is important to start with the domain rather than the range.
Answer:
A=78
B=102
C=78
Step-by-step explanation:
A= a and 102 are on a straight line so they add up to 180. 180-102=78. The same goes for C
B= the vertical angle for 102, or the same thing with a and c, just flipped around
