For this case we have the following product:

\sqrt{2}(5+\sqrt{8})

Applying the distributive property we have:

5\sqrt{2}+\sqrt{2}\sqrt{8}

Then, rewriting the expression we have:

2\sqrt{2}\sqrt{2}+5\sqrt{2}

4+5\sqrt{2}

We note that the answer is a irrational number, because the square root of two is not an exact number.

Answer:

4+5\sqrt{2}

It is irrational and equal to 4 + 5square root of 2.

We are given with two factors: square root of 2 and 5 + square root of 8. We use a scientific calculator that displays irrational answers. The product of the two factors is 4 + 5 square root of 2. The answer is irrational since the square root sign in the answer is present.

Dmitry_Shevchenko [17]
The greatest common factor is the product of shared primes of the numbers prime factorizations.

32=2*2*2*2*2, 80=2*2*2*2*5  So the GCF is 2*2*2*2=16

So there will be 16 teams with 2 forwards and 5 guards each.

Lunna [17]

Answer: 6.5 feets

Step-by-step explanation:

The model of the spaceship was made to a scale of 1:16. Assuming the same unit of measurement used in the actual spaceship was also used in the model space ship and it was in feets. This means 1 foot on the model spaceship represented 16 feets on the actual spaceship.

In the movie, the ship is supposed to be 104 feet long. Let x be the corresponding length on the model. Therefore,

1:16 = x:104

1/16 = x/104

16x = 104

x = 104/16 = 6.5feets

So the length of the model is 6.5 feets
