In general, any decimal that ends after a number of digits such as 7.3 or −1.2684 is a rational number.

A monomial of the 2 degree with a leading coefficient of 3

Ilia_Sergeevich [38]

Answer:

In the procedure

Step-by-step explanation:

we know that

A polynomial which has only one term is called monomial

The degree of a monomial is defined as the sum of all the exponents of the variables

<em>Examples</em>

If the monomial has only one variable

3x² -----> is a monomial of the 2 degree with a leading coefficient of 3

If the monomial has more than one variable

3xy ----> is a monomial of the 2 degree with a leading coefficient of 3

#24 please I need help this is due 8 hours from now!

Since it's asking you to write a problem about a sharing division "situation", I'm assuming the picture above it is part of #4 so you could use that as a reference as well.

You could do 2 divided by 5 which is left with a remainder. So it could be like, "Jack has 5 cookies and wants to share with his friends, he wants to give each of his two friends 2 cookies each".. Something like that and you go ahead and solve it. The final answer will be the solution to your word problem. I hope this helped

12n^3 + 16n^3 can someone please help me with this?

vodka [1.7K]

Answer:

$4n^{3} (3n^{2} + 4)$

Step-by-step explanation:

Assuming the problem is asking you to factor out the formula, it can be done easily by finding a common number with the two givens.

4 goes into both 12 and 16 evenly, so we will use this to factor. But that's not all, we have the n-variable to worry about.

Look at the n-variable exponents in the problem, take the highest power that can go be subtracted from both and use that. We have a $n^{5}$ and $n^{3}$ . Since 5 can't go into 3, we must use 3 to factor.

Our factoring variable will therefore be $4n^{3}$ . Now, use this to simply divide and get the answer:

$( 12n^{5} + 16n^{3} ) / 4n^{3} = 4n^{3}(3n^{2} + 4)$

So how did we get this? For the whole numbers, we have to divide: (12/4, 16/4). Next, we have to minus the exponents since we are dividing.

When dividing the 12 and 4, minus the $n^{5}$ and $n^{3}$ to get $n^{2}$ . Get rid of the $n^{3}$ term for the 16 and leave the 4. And there's your answer!
