What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?

(x+3)(x+7)

step-by-step explanation:

b and c

step-by-step explanation:

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!
