To calculate the distance between 2 points we will use the following equation:
![D=\sqrt[]{(x_2-x_1)^2-(y_2-y_1)^2}](https://tex.z-dn.net/?f=D%3D%5Csqrt%5B%5D%7B%28x_2-x_1%29%5E2-%28y_2-y_1%29%5E2%7D)
For this exercise we have the following data:

We plug the values into the distance equation and solve for the unknown Y
4x-2x-7x= -5x
-5-3=-8
-5x-8
Answer:
n= 12
Step-by-step explanation:
12 times 2 gives you 36
12 times 4 gives you 48.
12 is both factors of these numbers
The probability will be :
C(12,2) / C(40,2) = 11/130, which is around 8.46%
Option A is correct.
Put the values of x in 3^x and you will get the answer corresponding to option A
