for the given expression.
<h3>What is simplification?</h3>
The process of reducing the complex mathematical expressions into the simplest form is called as the simplification.
here we have two expressions.

We can write the expression as:

Answer: Yes
Step-by-step explanation:
The following is an example of a cluster sampling.
Cluster sampling<span> is a </span>sampling<span> technique used when "natural" but relatively heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this technique, the total population is divided into these groups (or </span>clusters) and a simple randomsample<span> of the groups is selected.</span>
When x=1 and -2 so it is C
In this equation x=-1/15 or negative one fiftenth.
