Question

If the distance between the points (2, 2) and (-1, x) is 5, one of the values of x is
(a) -2 (b) 2 (c)-1 (d) I​

Answer 1

Answer:

a) -2

Step-by-step explanation:

Distance between the points (2, 2) and (-1, x)

= √(2-(-1))^2 + (2-x)^2 = 5 (given)

√3^2 + (2- x)^2 = 5

9 + 4 - 4x + x^2 = 25

x^2 - 4x - 12 = 0

(x-6)(x+2) = 0

x = 6, -2

So, one value of x is -2
