PH is calculated by the negative logarithm of the hydrogen concentration in a solution. Therefore, the pH in this case is:
pH = -log (0.0000006)
pH = 6.22
Therefore the correct answer among the choices is the last option, pH of 6 with a color pink.

Answer:
x = 8
Step-by-step explanation:
For this question, you can use power of a point, more specifically when two secants intersect in the interior of a circle. From this, you get the equation:
(7 + x)(12) = (10)(2x + 2)
You can simplify and solve:
84 + 12x = 20x + 20
84 = 8x + 20
64 = 8x
x = 8
Going down the chart:
6
4
3
4
6
the brackets on the outside of the lxl makes the value positive or keeps the value positive. therefor if u have y=l-3l+3 y will still =6! hope this helps!
