Answer:
4x-14
Step-by-step explanation:
8x-(14+4x)
8x-14-4x
8x-4x-14
4x-14
(60 minutes / 8 km)*(2 km) = 60/4 = 15 minutes
That is the pH scale
pH = - log of the concentration of hydrogen ions in a solution.
You can't factor anything out of this except for a number. In this case, you can factor out a four. 16/4=4 40/4=10. This written out should look like 4(4x+10y), and that is your answer.
