The coordinates of the vertices of quadractical jklm are j(-3,2), k(4,-1), l(2,-5), and m(-5,-2). find the slope of each side of the quadractical and determine if the quadractical is a parallelogram

Right side of the quadrilateral's slope: 
(-1 - (-5))/(4 - 2) = 2 
Left side of the quadrilateral's slope: 
(2 - (-2))/(-3 - (-5)) = 2 
These have the same slope, so they are equal.

Top side of the quadrilateral's slope: 
(-1 - 2)/(4 - (-3)) = -3/7 
Bottom side of the quadrilateral's slope: 
(-2 - (-5))/(-5 - 2) = -3/7 
These also have the same slope so they are also equal.

Because the left and right sides are equal and the top and bottom sides are equal, we can say that the quadrilateral is a parallelogram.

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
