1. Distance = sqrt((2 – -3)^2 + (-5 – 0)^2) = sqrt((-5)^2 + (-5)^2) = sqrt(25 + 25) = 5*sqrt(2) (D)
2. AB+BC = AC ==> 4x+7x = 11x ==> AC = 11x
IF AC = 55 and
AC = 11x, then
55 = 11x
5 = x
AB = 4x = 4*5 = 20 (B)
3. Find the midpoint of the points (2,-5) and (-3, 0).
Find the average of the X values and the y values
X: (2 + -3) / 2 = -1/2
Y: (-5 + 0) / 2 = -5/2

we can use it if you’re going to be an engineer or a math instructor or you can also aid your kids with geometry one day and if now not you have got to be taught it because it makes your mind paintings and it’ll make you extra Intelligent and it is extremely well and it’s exciting
