thank you

Answer 2

The value of x is $2\pm 2\sqrt{6}$

Step-by-step explanation:

Since we have given that

(-2,2) and (-1,x)

Distance between them = 5

As we know the formula for distance between two coordinates.

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=5\\\\(-1+2)^2+(x-2)^2=5^2\\\\1^2+x^2+4-4x=25\\\\x^2+5-4x=25\\\\x^2-4x=25-5\\\\x^2-4x=20\\\\x=2\pm 2\sqrt{6}$

Hence, the value of x is $2\pm 2\sqrt{6}$
