2x-2y=6
4x+4y = 28
4x - 4y = 12
4x + 4y = 28
8x = 40
4x+4y = 28
8x = 40
previous activity

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

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!

i think the answer is c sorry if it's wrong

the answer for the second equation is (4,0)
