Answer:
the answer is 32 units.
Step-by-step explanation:
In an equation like that, y would double into 2y. But just keep in mind that what happens to one side must happen to another.
You basically just get a equation that needs to be answered and grab the answer and minus it by one of the two digits in front. Example: 3+2=5 is equal to 5-2=3
<u>Given</u>:
The number 12 is the geometric mean between 3 and a number x.
We need to determine the value of x.
<u>Value of x:</u>
Since, we know that the geometric mean is the square root of the product of two numbers.
Hence, we have;
where a and b are two positive numbers.
Substituting Geometric mean = 12, a = 3 and b = x, we get;
Squaring on both sides, we get;
Dividing both sides of the equation by 3, we have;
Thus, the value of x is 48.
