The bears (B), lions (L), rams (R) and panthers (P) at the zoo are located as vertices on the diagram below. The distance from the lions to the bears is 18 m. What is the distance from the lions to the rams (x) and the distance from the panthers to the lions (y)?
A
B
C
D

b.-4 units

all you   do is count how many times you move

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
