In the diagram below of triangle GHJGHJ, KK is a midpoint of \overline{GH} GH and LL is a midpoint of \overline{HJ} HJ . If KL=8x-2KL=8x−2, and GJ=32-2xGJ=32−2x, what is the measure of KLKL?

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

correct

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
