One of the most important mathematical problems through all times has been to find the area of a polygon. for example, real estate areas often had the shape of polygons, and the tax was proportional to the area. suppose we have some polygon with vertices ("corners") specified by the coordinates (x1,y1), (x2,y2), (xn, yn), numbered either in a clockwise or anticlockwise fashion around the polygon. the area a of the polygon can amazingly be computed by just knowing the boundary coordinates:

what are you trying to solve here

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
