Answer:

1) ( 6+\sqrt{6} ) / 2                 2) 2 \sqrt{3} - 3

Step-by-step explanation:

I got the same thing as the other person, but typing it out would take forever just to give you the same result.

You do use a technique called rationalizing a denominator to eliminate the radical. The point of rationalizing a denominator is to make it easier to understand what the quantity really is by removing radicals from the denominators.

1) ( 6+\sqrt{6} ) / 2

2) I got the same answer but I put in 1 more step. It looks like the person caught it though.

From the -3 + \sqrt{12}    

-3 + \sqrt{4} \sqrt{3}

-3 + 2 \sqrt{3}     Rearrange

2 \sqrt{3} - 3

The volume of a conical pile of sand is increasing at a rate of 300πcm3/sec
lesya [120]
So using the formula for the volume of a cone:
r^2pi x h/3

The height is always 4 times the radius, so:
h=4r

Now putting the values into the original formula:

r^2pi x 4r/3

Now to see how much the radius increases per second:

r^2pi x 4r/3=300pi

r^2 x 4r/3=300

r^2 x 4r=900

r^2 x r=225

r^3=225

The radius increases by the cubic square root of 225 cm per second.

f(s)= 225^1/3 cm

??????????????????????????????
Greeley [361]

\large\displaystyle\text{$\begin{gathered}\sf \frac{2x-20}{3}=2x  \end{gathered}$}

Multiply both sides of the equation by 3.

\large\displaystyle\text{$\begin{gathered}\sf 2x-20=6x \end{gathered}$}

Subtract 6x on both sides.

\large\displaystyle\text{$\begin{gathered}\sf 2x-20-6x=0 \end{gathered}$}

Combine 2x and −6x to get −4x.

\large\displaystyle\text{$\begin{gathered}\sf -4x-20=0 \end{gathered}$}

Add 20 to both sides. Any value plus zero results in its same value.

\large\displaystyle\text{$\begin{gathered}\sf -4x=20 \end{gathered}$}

Divide both sides by −4.

\large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{-4}  \end{gathered}$}

Divide 20 by −4 to get −5.

\large\displaystyle\text{$\begin{gathered}\sf x=-5 \ \ \to \ \ \ Answer \end{gathered}$}
