Hey, could you make your question and LaTeX more clear? Thanks! 

1, 2, 7, 16, 29........etc.

The "closed form" of your sequence appears to be:

a_n = 2 n^2 - 5 n + 4 . Hence the 100th term is:

a(100) =2*100^2 - 5*100 + 4

a(100) =19,504

Here is one answer

Do you have, or can you find the address of where this was asked last time?

It really is polite to continue it on the original thread, and it is also better for future people who might find it in a search.

\(-\sqrt{2}+1\)or \(\sqrt{2}+1\)

The LCM is x^4 - 2x^3 + 4x^2 - 6x + 1.

The solutions are x = 1 and x = 2.

The remainder is 6x^2 - 3x + 1.

Hi ilorty,   

It is in raw form, and I would not normally answer.

But so many people have said that the code does not always render properly these days that I gave them the benefit of the large doubt.

I probably should not have, I think it is only guest posts that have had this problem.

I need help with this.

\(\begin{array}{|rcll|} \hline 155+10x &=& 320 - 15x \\ 15x+10x &=& 320 - 155 \\ 25x &=& 75 \\ x &=& \dfrac{75}{25} \\ \mathbf{x} &=& \mathbf{3} \\ \hline \end{array}\)

After 3 weeks will their savings account have the same amount of money in them.

all you have to do is find this: y=[slope]x+[y-intercept]

(which is what gwen did )

:)

hey! is it just me, or is the latex in raw form? just wondering if it's a glitch!

:)

By the way, I found a helpful link - this might be helpful. It uses the same method I used but it explains it better than I did.

https://math.stackexchange.com/questions/1873138/distribution-of-4-distinct-balls-into-5-identical-boxes-without-any-restrictions#:~:text=There%20are%202%20ways%20to,6%C3%972%3D12%20cases.

Assuming order matters:

There are 5 cases, {4}, {3,1}, {2, 2}, {2, 1, 1}, and {1, 1, 1, 1}.

{4} - 4! which is 24

{3, 1} - 4 x 3! - 24 (4 ways to pick the single one and 3! ways to rearrange the others)

{2, 2} - 6 x 2 = 12 (6 ways to choose the pairs, and two ways to order the pairs)

{2, 1, 1} - 12 (6 ways to choose the pair and two ways to order it)

{1, 1, 1, 1} - 1 (just one way to order it)

24+24+12+12+1 = 73.

I hope this helped.

If possible get some blocks and use them to answer the question

How many blocks altogether  3*3*3=27  (you are told that anyway)

1. What is the max number of sides that can be painted on any individual little block?

2. How many in the middle with no paint?

3. Which ones have 3 sides painted?  How many are there?

4. How many have only one side painted, where are those ones?

5. How many blocks have been accounted for so far?

5. The rest must have 2 sides pained, how many is that?

Now answer the question.

Please allow original guest to answer these questions. 

\(x=0.75y\\ \frac{2x+y}{3x-2y}\\ =\frac{1.5y+y}{3*0.75y-2y}\\ =\frac{2.5y}{2.25y-2y}\\ =\frac{2.5y}{0.25y}\\ =\frac{2.5}{0.25}\\ =10 \)

Haha lol 😂

-4*-2.3*23

-4*-2.3*23 = 211.6

what are you talking about?

I do not think that this is possible.

Are you sure your question is copied properly?

PB = √22 

Well, this is my answer.

y=-3/2x+4.

1. A straight angle equals 180° and to bisect means to cut directly in the middle or cut directly in half.

2. Let angle EBA be x. The equation for solving this problem will be x=(180°-130°)/(2).

3. x=(180°-130°)/(2)=50°/2=25°. x=25°

Answer: Angle EBA=25° 

Thank you so much! :D
