The option that shows what all the polygons have in common is that;
B. Each appears to have exactly one pair of parallel sides.
<h3>Polygon</h3>
Looking at the polygons given, we can see that;
- Polygon A has 4 sides and one pair of parallel sides and it is a quadrilateral because it has 4 sides.
- Polygon B has 4 sides and one pair of parallel sides and it is a quadrilateral because it has 4 sides.
- Polygon C has 6 sides and so is not a quadrilateral but a hexagon and it has a pair of parallel sides.
- Polygon D has 5 sides and so is a pentagon but has a pair of parallel sides.
Looking at all the polygons the only common statement is that they a pair of parallel sides.

Answer:
Option B is correct.
the value of discriminant is, -7
Step-by-step explanation:
Given the equation: 
To find the value of discriminant 
A quadratic equation is of the form 
where a, b and c are coefficient of the equation.
On comparing with given equation we have;
a = 1 , b = 1 and c = 2
then;
Discriminant = 
Therefore, the value of discriminant is, -7
