Answer:
The equivalent expression can be given as:
⇒ 
Step-by-step explanation:
Given expression:
To write an equivalent expression:
Solution:
In order to write an equivalent expression, we will combine the like terms. By like terms, we mean the terms with the same variable constant.
For example : 
and 
are like terms.
We have:
Combining like terms :
⇒ 
⇒
Thus, the equivalent expression can be given as:
⇒

Answer:
- octagon
- irregular polygon
- concave
Step-by-step explanation:
The figure has 8 sides that are each line segments joined at the ends. An 8-sided polygon is called an <em>octagon</em>. Though the sides are the same length, not all angles are congruent, so the polygon is <em>not a regular polygon</em>. Some of the angles are reflex angles, so the polygon is <em>concave</em>, not convex.
