Question

find the value of x,if the distance between the points (x,-1) and (3,2) is 5. x=7,x=-1​

Answer 1

Answer:

X=7 or -1

Step-by-step explanation:

Applying distance formula,

$\sqrt{(x-3)^{2}+(-1-2)^2 }$=$\sqrt{25}$

squaring both sides, we get,

(x-3)²+9=25

=>(x-3)²=16=(±4)²

Taking square root of both sides, we get

=>x-3=4 or x-3= -1

=>x=7 or x= -1
