Answer: $10\sqrt{3}$

Step-by-step explanation:

Since both radicals have the same index (square roots) then to multiply them you simply multiply the numbers under the square root signs and keep them there:

$\sqrt{30} \sqrt{10}=\sqrt{300}$

Then, to simplify the expression you can break down the number into its factors till you get a perfect square that you can get out of the square root. In this case, since 300 is divisible by 100, then we're going to break it down conveniently because 100 is a perfect square:

$\sqrt{300}=\sqrt{3*100}=10\sqrt{3}$

There is a competition in the cinema to win free tickets. You must guess the ages of the four employees. Here are the clues: - W

Answer:

Kirk is 28 years old, Brian is 36 years old, Matt is 18 years old, and the manager is 24 years old.

Step-by-step explanation:

Let $k$ be Kirk's age.

Let $b$ be Brian's age.

Let $m$ be Matt's age.

Let $m_{1}$ be the boss/manager's age.

From the information given, we can set up 4 equations:

$k+b+m+m_{1}=106$

$k=2(m_{1}-10)$

$b=2m_{1}-12$

$m=\frac{1}{2}m_{1}+6$

Rewrite the first equation, substituting $k$ , $b$ , and $m$ in terms of $m_{1}$ to get:

$2(m_{1}-10)+(2m_{1}-12)+(\frac{1}{2}m_{1}+6)+m_{1}=106$

Open up the parentheses using the distributive property (which is $a(b-c)=ab-ac$ ) and combine like terms to get:

$5.5m_{1}-26=106$

Add 26 to both sides to reach:

$5.5m_{1}=132$

Thus, $m_{1}=24$ . Substitute $24$ for $m_{1}$ in the second, third, and fourth original equations to find that $k=28$ , $b=36$ , and $m=18$ . Therefore, Kirk is 28 years old, Brian is 36 years old, Matt is 18 years old, and the manager is 24 years old. To check, you can add up all of the ages to get 106.

Hope this helps :)
