Answer: I think its 4 + 2m
57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20

Answer:
C. 
Step-by-step explanation:
Given: 
To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.


So since x is greater than zero, we have just found out our domain:

Answer:
=6x+3y
Step-by-step explanation:
3X+3(X+Y)
Distribute:
=3X+(3)(X)+(3)(Y)
=3X+3X+3Y
Combine Like Terms:
=3x+3x+3y
=(3x+3x)+(3y)
=6x+3y
