Answer 3

I think it's C... But I'm not sure. It's just a guess!

Answer 4

48+20sqrt3 -12sqrt3 -15 =
=33+8sqrt3

D) is right

do you understand it how ???

Answer 5

How did you get that answer?

Answer 6

4*12=48
4*5sqrt3=20sqrt3
-sqrt3 *12 =-12sqrt3
-sqrt3 *5sqrt3=-5*3=-15

48-15=33
20sqrt3 -12sqrt3=8sqrt3

33+8sqrt3

ok ?
