Answer:
The answer is in the picture. I hope it is helpful.
The answer is D. First, it is the segment addition postulate because the two segments make up the whole. Second, it's substitution because you are substituting EF + FG for FH.
Hope this helps!

Answer:
The concentration of hydrogen ions in moles per liter (M) is ![3.981 * 10^{-9}](https://tex.z-dn.net/?f=3.981%20%2A%2010%5E%7B-9%7D)
Step-by-step explanation:
As we know
The hydrogen ion concentration of any solution at pH is given by
![H^+ = 10^{-pH}](https://tex.z-dn.net/?f=H%5E%2B%20%3D%2010%5E%7B-pH%7D)
Substituting the given values in above equation, we get -
mol/l
The concentration of hydrogen ions in moles per liter (M) is ![3.981 * 10^{-9}](https://tex.z-dn.net/?f=3.981%20%2A%2010%5E%7B-9%7D)
Answer:
<u>x = -8</u>
4x + 8 = 2x - 8
3x + 4 = 2x - 4
2x + 16 = x + 8
x - 1 = 2x + 7
17x + 36 = 16x + 28
13x + 2 = 12x + 11
.......
(this is infinite)
As long as it cancels out to x = -8
