The answer should be 4.

First, simplify to 4. Your problem should look like: 4 x 1.
Second, multiply. 4 x 1 = 4 so that is your answer.

Also, to start the equation up, make sure to add in the numbers in replace for the letters. Your problem to start with should look like: .

Your family goes to a Southern-style restaurant for dinner. There are 6 people in your family.

Answer:

We conclude that:

The number of people who ordered the chicken dinner = 1

The number of people who ordered the steak dinner = 5

Step-by-step explanation:

Given that

Some order the chicken dinner for $14

some order the steak dinner for $17.

Total bill = $99

Let 'n' be the number of people who ordered the chicken dinner.

Let '6-n' be the number of people who ordered the steak dinner.

Thus, the equation becomes

$14n + 17(6-n) = 99$

$14n + 102 - 17n = 99$

$-3n = 99 - 102$

$-3n = -3$

Divide both sides by -3

$n = 1$

and

$6-n = 6-1 = 5$

Therefore, we conclude that:

The number of people who ordered the chicken dinner = 1

The number of people who ordered the steak dinner = 5

Simplify<br><br> sqrt(3 + 2 sqrt 2) ...?

trasher [3.6K]

The answer is 1 + √2

sqrt(2) is $\sqrt{2}$
sqrt(3 + 2 sqrt 2) is $\sqrt{3 +2 \sqrt{2} }$
Now, let's simplify $\sqrt{3 +2 \sqrt{2} }$ .
We will use square of sum: (a + b)² = a² + 2ab + b²

$\sqrt{3 +2 \sqrt{2} } = \sqrt{1+2+2 \sqrt{2} }= \sqrt{1+2 \sqrt{2}+2 }= \\ 
= \sqrt{1^{2} +2*1* \sqrt{2} + (\sqrt{2} ) ^{2} } = \sqrt{(1+ \sqrt{2}) ^{2}} =1+ \sqrt{2}$
