Solve for x & show your work :)
5 ( 3x - 9) = 2 ( 6x + 9)

x = 21

Step-by-step explanation:

Given

5(3x - 9) = 2(6x + 9) ← distribute parenthesis on both sides

15x - 45 = 12x + 18 ( subtract 12x from both sides )

3x - 45 = 18 ( add 45 to both sides )

3x = 63 ( divide both sides by 3 )

x = 21

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!
