Answer:

√a(√a + 2) a - 2√a

----------------- = -----------------

a - 4 a - 4

√a

----------

√a - 2

To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:

OLEGan [10]

Answer:

960 sprinkles

Step-by-step explanation:

x = sprinkles

For this problem we will create a ratio

$\frac{24}{384} :\frac{60}{x}$

24x=384*60

24x=23,040

x=23,040/24

x=960

Stan would need 960 sprinkles!

Hope this helps!
