Question

if the distance between the points(3,2) and (-1,x) is 5 then value of x is:​

Answer 1

Answer:

Correct option is A

Step-by-step explanation:

Correct option is

A

x = 7

B

x= -1

Distance between two points (x1,y1) and

(x2,y2) can be calculated using the

formula (x2−x1)2+(y2−y1)2

Distance between the points (x,−1) and (3,2)=5

=>(x−3)2+(−1−2)2=5

(x−3)2+9=5

(x−3)2+9=25

(x−3)2=16 

x−3=+4  or −4

x=7 or x=−1
