Which expression has a coefficient with the same value as 3 ( 2 ) + 4 ? A. 3 + 10 n B. 3 + 9 n C. 3 n − 6 D. 6 n − 10

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!
