Question

if the distance between the points {2, - 2} and {1 - X }is 5 one
of the value of x is​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

let A(2,-2) and B(1,-X)

distance of (AB)2

$5= ( {2 - 1)}^{2} + ( { - 2 + x})^{2}$

$5 = 1 + 4 + {x }^{2} - 4x$

$5 = 5 + {x}^{2} - 4x$

${x}^{2} = 4x$

now on solving

$x = 4$
