Can someone explain this to me.
almond37 [142]

Answer:

option D

3*(\sqrt{x}+\sqrt{x-3})

Step-by-step explanation:

Given in the question an expression,

\frac{9}{\sqrt{x} -\sqrt{x-3}}

Step 1

Divide and multiple by \sqrt{x}+\sqrt{x-3} to remove radical sign from denominator.

\frac{9}{\sqrt{x} -\sqrt{x-3}}*\frac{\sqrt{x} +\sqrt{x-3}}{\sqrt{x} +\sqrt{x-3}}

Step 2

Apply a² - b² = (a+b)(a-b)

\frac{9*\sqrt{x}+\sqrt{x-3}}{\sqrt{x^{2}}-\sqrt{(x-3)^{2}}}}

Step 3

\frac{9*\sqrt{x}+\sqrt{x-3}}{x-x+3}

Step 4

\frac{9*\sqrt{x}+\sqrt{x-3}}{3}

Step 5

3*(\sqrt{x}+\sqrt{x-3})

sleet_krkn [62]
2/5 of 20 = 8. 

3/10 of 20= 6. 

8+6=14. So 20-14= 6

She needs 14 pints, so you subtract 6 from that. Your final answer should be 8 pints.
