Answer: 6
Step-by-step explanation:
Slope is found by doing:

(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)
Let us say that (x1,y1) is (3,18)
And (x,y) is (5,30)

Add the opposite of any terms that don't have r.
.. K +7s = 4r
Divide by the coefficient of r.
.. (K +7s)/4 = r
Answer:
x= -54
Step-by-step explanation:
distribution- -8x-36+3x=6-4x+12
add like terms- -5x-36=-4x+18
get x alone -5x=-4x+54. added 36 to both sides
add 4x to both sides -x=54
divide by -1. x= -54
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.
