Question

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

Answer 1

Answer: x=-1

Step-by-step explanation:

Distance between the points (x, -1) and (3, 2) is

$\sqrt{(3-x)^{2}+ (2-(-1))^{2} }$ = 5

or, $(3-x)^{2}+ 3^{2}= 5^{2}$

or, $(3-x)^{2}=25-9=16=4^{2}$

or, 3-x=4

or, x=-1
