Question

How do you find x so distance between the points (6, -1) and (x, 9) is 12?

Answer 1

Answer:

Step-by-step explanation:

the square of the distance between the given points is

(x - 6)^2 + (9 + 1)^2 = 144

(x - 6)^2 + 100 = 144

(x - 6)^2 = 44

x - 6 = +- sqrt(44) = +- 2sqrt(11)

x = 6 +- 2sqrt(11).
