Question

if the distance between a ( X,1) and b (8 ,9) is 10 units find the value of x​

Answer 1

Answer:

X=2,14

Step-by-step explanation:

Given: AB= 10 units

A=(X,1) B=(8,9)

As, AB=((X-8)²+(1-9)²)^½

or 10²= X²+8²-2×8X+(-8²)

or 100= X²+64-16X+64

or X²-16X+128-100=0

or X²-16X+28=0

or X²-14X-2X+28=0

or X(X-14)-2(X-14)= 0

or (X-2)(X-14)=0

or X=0+2 X=0+14

or X=2 X=14

or X= 2,14
