An equilateral triangle has 3 sides of equal length
find the length of 1 side and that is the length of te other 2 sides
so find the length and times 3
we need to find the distance betwen the points (-8,-5) and (3,7)
distance between the points (x1,y1) and (x2,y2) is

so
distance between (-8,-5) and (3,7) is




the distance is √265
the perimiter is 3√265 units
The answer is the last one -4 < x < 1/2
