The answer is would have to be b.
Answer:
A
Step-by-step explanation:
The statement "If x = 3, then x^2 = 3x" was formed by multiplying x = 3 by x on both sides. Thus x = 3 becomes x*x=3*x. This simplifies to x^2 = 3x. This property is the multiplication property of equality.
Answer:
The common for the second question is 30
First you gotta do rise over run. then once you do that, you should get your answer. which is x=-4
ok. We are given the following equation:

Where:

Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:

Now, we will use the following property of logarithms:

Applying the property and having into account that:

We get:

Now we substitute the given value of "pH = 4.5":

Solving the operation:

Therefore, the hydrogen ion concentration of the fluid is 0.000032
