Combine the following expressions:

melisa1 [442]

ANSWER

$(4n - 1)\sqrt{3 n} + 3\sqrt{n}$

EXPLANATION

The given expression is

$\sqrt{48 {n}^{3} } + \sqrt{9n} - \sqrt{3n}$

We remove the perfect squares under the radical sign.

$\sqrt{16 {n}^{2} \times3 n} + \sqrt{9n} - \sqrt{3n}$

We can now take square root of the perfect squares and simplify them further.

$\sqrt{16 {n}^{2}} \times \sqrt{3 n} + \sqrt{9} \times \sqrt{n} - \sqrt{3n}$

This simplifies to:

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

This further simplifies to:

$(4n - 1)\sqrt{3 n} + 3\sqrt{n}$

Properties of a circle:

ExtremeBDS [4]

Tangent is a line that touches the circle at one point going infintiely in both directions

chord is a line that goes from one side of the circle to the other and stays inside the circle, an example would be the diameter which is the longest chord in the circle

secant is a line that goes through the circle at 2 points, it's like a chord but it extends outside the circle

arc length is a section of the circumference
it's like the length of the crust when you cut a slice of pie or the crust of a pizza

PLEASE HELP if Suzy can drive 4/5 miles in a half hour how many miles can she drive in 1 hour FOR A TEST PLEASE ANSWER

kati45 [8]

Since you are trying to figure out how many miles she can drive in 1 hour and you already have half of that hour, all you would need to do is double that number.
$\frac{4}{5}$ × $\frac{2}{1}$ = $\frac{8}{5}$

Now, all you would need to do is simplify the answer.
$\frac{8}{5}$ = 1 $\frac{3}{5}$ or 1.6

The answer would be, Suzy can drive 1 $\frac{3}{5}$ or 1.6 miles in 1 hour.

I hope this helps!
