1 answer:
Answer: 4
Step-by-step explanation:
We know that a plane is 2 dimensional surface that extends infinitely far.
The number of points required to define a plane = 3
Here , we have 4 points A, B, C, and D.
So, the number of possible combinations of 3 points to make a plane from 4 points =
[
]
Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.

Using perfect squares simplification, it is found that the value of the desired limit is of -4.
<h3>When is a limit?</h3>It is the value of a function as x approach
In this problem, the limit we want to find is given by:
If we just replace x by -2, we end with an undetermined limit, as we have 0/0.
However, the perfect square simplification states that:
a² - b² = (a - b)(a + b).
Hence:
x² - 4 = (x + 2)(x - 2).
Then:
Hence, the value of the desired limit is of -4.
