Ответ:
do u have to use the exact same number for all the substitutions?
Ответ:
Point A
2/3 A= -24
A = -24 / 2/3
A = -24 * 3/2
A =-36
Point B
20 = -B / 0.20
20 * 0.20 = -B
4 = -B
4 / -1 = -B/ -1
The distance from point A to the origin is = 36
distance from point B to the origin is = 4
distance from point A to B = 36 + 4 = 40
The distance between the two points is 40
