A. 4.0
b. 16.0
c. 12.5
d. 11.7

D

Step-by-step explanation:

to find the answer you do the square root of (x2-x1)^2+(y2-y1)^2.

So you just plug it in and get the equation of

the square root of (-4-2)^2+(-8-2)^2 which equals 11.66190379

then you round to the tenths which then comes out to 11.7

D. 11.7

Step-by-step explanation:

= √(−4−2)^2 + (−8−2)^2

= √(-6)^2 + (−10)^2

= √36 + 100

= √136

= 11.66 which rounds to 11.7

i would go with the first one
