Using Cramer’s Rule, what is the value of x in the solution to the system of linear equations below? 2/5X + 1/4Y = 9/20
2/3X + 5/12 = 3/4

A)X = 0
B)X = 1
C)There are no solutions to the system.
D)There are infinite solutions to the system.

A will be the correct for thus one

Concave and Hexagon.

Step-by-step explanation: In the given figure we have one angle is greater than 180 degrees.

A polygon has an angle between 180 to 360 is called a concave polygon.

Therefor given polygon is a concave polygon.

Also the given polygon has six sides.

A polygon with six sides is a hexagon.
