The answer choice which correctly models the range of pH values of bleach is; 11< x < 14.
<h3>What is.the range of values for the pH of bleach?</h3>
According to the task content; Bleach is said to have a pH of less than 14 and greater than 11.
Hence; pH < 14. and pH > 11.
Therefore, when written as a compound inequality; we have;
11< pH < 14.

Answer:
g(g(x)) = 4x + 9
Step-by-step explanation:
To obtain g(g(x)) substitute x = g(x) into g(x) , that is
g(g(x))
= g(2x + 3)
= 2(2x + 3) + 3 ← distribute parenthesis
= 4x + 6 + 3 ← collect like terms
= 4x + 9
Well, there's:
7 * 2 =14
and
7 * 3 = 21
Both of these have only the factor 7 in common. Therefore, it is the greatest factor. You can use any combination of numbers that have a factor of 7 and only 7 in common.
