I need help on my whole math book if someone wants 100 points first this one

B

Step-by-step explanation:

B is the only one without a variable(or unsimplified square root) and is 5 so it ends up as 5+1.25 or 6.25 which is a rational number

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

75%
