Answer:A, B and D

Step-by-step explanation:

A linear relationship is one in which when the variables are plotted, the graph would be a straight line. In a linear relationship, the highest power of the variables is 1. We would compare each of the given relations.

A) Double x and subtract five to get y. This is expressed as

2x - 5. It is a linear relationship.

B) Multiply x and y to get 20. This is expressed as

xy = 20. It is a linear relationship.

C) Multiply x times itself and add five to get y. This is expressed as

x^2 = y. It is not a linear relationship. The highest power of the variables is 2

D)Divide 40 by x to get y. This is expressed as

40/x = y. It is a linear relationship.

5 - 6 = -1

-1 - 9 = -10

-10 - 8 = -18

-18 - 5 = -23

-23 - 4 = -27

-27 + 5 = -22

-22 - 5 = -27

-27 -5 = -32

-32 -5 = -37

-37 - 32 = -69

Answer = -69

Before answering the given question, you should know the difference between polygon and regular polygon. 

Polygon :- It is closed figure constitute of straight line having different measurements and also having varies angles.
Regular polygon :- It is also a closed figure constitute of straight lines which having equal measuresment and all the angles of the given polygon are equal .

There are different types of polygon based on the sides :-

A polygon having 3 sided called triangle ,having 4 sides called quadrilateral ,having 5 sides pentagon and so on.

<h3>Let's Begin :-</h3>

I have thought to make a 4 side polygon that is quadrilateral.

Steps of construction :-

Step - 1 :- Draw a 5 cm line AB horizontally
Step - 2 :- Then , From a point B, Draw a Vertical line of 5 cm and named it BC
Step - 3 :- Then, From a point C, Draw a horizontal line of 5 cm and named it CD
Step - 4 :- Now, join the line AD
Step - 5 :- Measure all the angles form by the 4 sides of the quadrilateral.
