Marta is solving the equation S = 2πrh + 2πr^2 for h. Which should be the result?

olga_2 [115]

Answer:

h = $\frac{S}{2πr}$ - r

Step-by-step explanation:

The question requires you to make h the subject of the formula.

S = 2πrh + 2πr²

subtract 2πr² on both sides.

S - 2πr² = 2πrh - 2πr² - 2πr²

S - 2πr² = 2πrh

Dividing both sides by 2πr

(S - 2πr²)/2πr = 2πrh/ 2πr

h = $\frac{S}{2πr}$ - r

3x + 40 = 11x -24<br><br> What does x equal?

pogonyaev

First, you would have to do 11x + 3x Since you're combining like terms.

Now your problem is 14x + 40 = -24

Now you would do 40 - -24 which is now 40+24 and equal to 64.

Now you divide 14 by 64 and you get 4.5
