Answer:.

A total of 5 expressions can be simplified to 4n + 8.

Step-by-step explanation:

1. 2n + 2(n + 4)

= 2n + 2n + 2.4

= 4n + 8

2. $\textbf{4(n + 1)} + \frac{ \textbf{4n}}{\textbf{n}}$

= 4n + 4 + 4

= 4n + 8

3. 2³ + n³ + n

Since. 2³ = 8 we have:

8 + n³ + n

≠ 4n + 8

4. 5(n - 1) - (n - 13)

= 5n - 5 - n + 13

= 4n + 8

5. 4n + 8

= 4n + 8

6. $\frac{\textbf{10(4 + 2n)}}{\textbf{5}}$

= 10.2(2 + n)/5

= 2.2(2 + n)

= 4(2 + n)

= 8 + 4n

= 4n + 8

7. (2n + 1)² - 4n²

= 4n² + 2.2n . 1 + 1² - 4n²

= 4n² + 4n + 1 - 4n²

= 4n + 1

Hence, the answer.

A comet travels along a parabolic path around the Sun. The Sun is the focus of the path. When the comet is at the vertex of the

AlladinOne [14]

Remember that for a function of the form $y=a x^{2}$ , a parabola, the focus will be: $(0, \frac{1}{4a} )$ .
We know that the vertex of the parabola is (0,0), and the sun is the focus of the parabola; we also know that the focus is in the positive y-axis and when the comet is as its vertex, the distance between them is 60'000.000 km; therefore the focus of our parabola is (0, 60'000.000).
Now that we know the focus, we can find $a$ using the focus of the parabola:
$\frac{1}{4a} =60'000.000$
$1=(60'000.000)(4a)$
$1=240'000.000a$
$a= \frac{1}{240'000.000}$

Now, the only thing left is replacing the value of $a$ in our equation $y=a x^{2}$ :
$y=( \frac{1}{240'000.000)} ) x^{2}$
$y= \frac{ x^{2} }{240'000.000}$

We can conclude that the equation that represents the path of the comet is $y= \frac{ x^{2} }{240'000.000}$

A store clerk is bagging spices. He has 18 teaspoons of cinnamon and 30 teaspoons of nutmeg. Each bag needs to contain the same

By finding the maximum common factor between the number of spoons, we conclude that he must put 6 teaspoons per bag.

There will be 8 bags in total.

<h3>How many teaspoons of spice should the clerk put in each bag?</h3>

We know that the store clerk has 18 teaspoons of cinnamon and 30 spoons of nutmeg.

Now, we want to put these in bags, such that each bag contains the same number of teaspoons.

Then the number of teaspoons per bag must be a common factor of 30 and 18. (the minimum number of bags is what we get when we select the maximum common factor).

Decomposing these two numbers gives:

30 = 2*3*5

18 = 2*3*3

Then the maximum common factor is 2*3 = 6

This means that we need to put 6 teaspoons per bag.

And the total number of teaspoons is 30 + 18 = 48, dividing that by 6 we get:

48/6 = 8

There will be 8 bags.
