A=3  b=5  c=2
x = -b +-sq root(b^2 -4*a*c) / 2a
x = [-5 +-sq root(5^2 -4*3*2)] / 6
x = [-5 +-sq root(25 -24)]/6
x = [-5 +- 1] /6
x1 = -1
x2 = -4/6 = -2/3 = -.66666666666666

On a coordinate plane the coordianits of vertices the and t for a polygon are r(-7,3) and r (3,3) what is the length of side rt
NemiM [27]

The length is 10.


Since the two points share the same y-coordinate, the segment rt is horizontal.


This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.


So, we have


\overline{RT} = |-7-3| = |-10| = 10
