(1)
We can select any of the two points to be our first point, let's say, J(1,-4) is point 1, so J (x1,y1). In other words,
and by the same way, for K(-2,8). Therefore,
. By substituting these values in equation 1, we can deduce the following
Answer:
60
Step-by-step explanation:
x²=36×(64+36)
x=√3600
x=60
-3x+ 4=1 and -12x -27=324
