Answer:
28
Step-by-step explanation:
It helps to plot the points on a graph. It is easy to see that three of the sides are of length 6, and the remaining two are the hypotenuse of a 3-4-5 triangle, hence length 5.
3×6 +2×5 = 28
The perimeter of this polygon is 28 units.
Answer:
Step-by-step explanation:
The given relation is Q = {(x, y): (2, 8), (3, 27), (4, 64), (5, 125), . . .}
We can quickly recognize a pattern to write the equation of the given relation.
We can observe the following pattern among the x and y coordintaes.




We can see that the base of the powers on the right are the x-values of the relation and the values on the left are the y-values.
Hence, for any ordered pair (x,y), the equation is
