<h3>Why is that 4 is equals to 16
/-4?</h3>
In a mathematical expression when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.
In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence expression that is equal to -4 is 16/-4 which is means optionD is correct.
Therefore, option C is correct.

We have,
Height of a cone is 12 feet
Volume of the cone is 90 feet
It is required to find the area of the base of the cone.
The base of a cone is circular in shape.
The formula used to find the volume of a cone is given by :
here, 
(area of base of cone)
So, the area of the base of the cone is 
.
Answer:
Step-by-step explanation:
is given as the nth term of a sequence.
We want to find 
, which means we find the 7th term of the sequence.
Here, we simply substitute "7" into "n" of the formula given for to find the value of the 7th term of the sequence.
We show this below:
So the 7th term is "-15"
There is no different in both of them. if you used both of them in a math problem you would still get the same answer as if you use the other one.
