Certainement en ville, je suis sans doute. Personellement, la tranquilité à la campagne ne m'amuse jamais. J'aime bien le fait qu'en ville, c'est très animé et il y a beauco...

x^2 - 7x - 18

X coordinates = (-3+1)/2 = (-2)/2 = -1Y coordinates = (-3+3)/2 = (0) /2 = 0 Coordinates of the midpoint = (x,y) = (-1,0)

h² = 25So firstly, we must square root each side of the equation.(square root) h² = (square root)25.so... h= (square root)25.h=5. or h=-5.
