The perimeter of the polygon is 26.1 units.
To find the perimeter of the polygon.
<h3>What is polygon?</h3>
A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
Given that:
Distance between points
,
is given by

As per the graph,
point Q is (2,0)
point R is (4,5)
point S is (8,7)
point T is (6,4)
point U is (10,3)
QR=

RS=

ST=

TU=

QU=
Perimeter refers to sum of lengths of all the sides.
Perimeter =5.38+4.47+3.60+4.12+8.54=26.1 units
So. the perimeter of the polygon is 26.1 units.

Answer:
mean
Step-by-step explanation:
Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
