Can someone help me please!!

Answer 1

Answer:

B

Step-by-step explanation:

Subtract

Answer 2

B. 

When you simplify the equation with the 180 surface area, you get the sqrt(30). This does not simplify any further. 

When you simplify the equation with the surface area of 120, you get sqrt(20), which simplifies further to 2sqrt(5). 

Then just subtract the second from the first.
