Answer:

2\sqrt{6}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{96}

= \sqrt{16(6)}

= \sqrt{16} × \sqrt{6} = 4\sqrt{6}

\sqrt{24}

= \sqrt{4(6)}

= \sqrt{4} × \sqrt{6} = 2\sqrt{6}

Thus

\sqrt{96} + 2\sqrt{6} - 2\sqrt{24}

= 4\sqrt{6} + 2\sqrt{6} - 4\sqrt{6} ← collect like terms

= 2\sqrt{6}

Answer:

<h2>2 \sqrt{6}</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • simplifying redical
  • PEMDAS

first thing

in your question about 70% is done so need to simplify it a little

\sqrt{96}  + 2 \sqrt{6}  -  2\sqrt{24}

\sqrt{ {4}^{2} \times 6 }  +  2\sqrt{6}  - 2 \sqrt{2 ^{2} \times 6 }

4 \sqrt{6}  + 2 \sqrt{6}  - 4 \sqrt{6}

<h2>2 \sqrt{6}</h2>

when the temperature is 68 F, the speed of sound in air is approximately 343 meters per second. Approximately how many kilometer
Digiron [165]

Hello!

Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.

343 · 5 = 1715 meters per 5 seconds.

1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.

1715 / 1000 = 1.715

Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds.
