Free homework help here

No you did it right, 6 is the answer.

Also, this is a homework help thread, not a do my homework for me.

It doesn't really need an explanation. (sort of) I tried giving an explanation in the bold, but that wasn't much of an explanation.

I just can't explain equations. That one is just self-explanatory (for me anyways)

Can anybody help me find a GOOD Integration using Substitution tutorial? I've been searching google video for 20 minutes and all of them are sub-par.

Post up some questions you don't understand and I'll work through them with you, if you want.

I need to write a paper on a religious war. Doesn't matter how long ago or where.

Will someone help me? Work of a 10th grader, smart student. Or atleast give me a few links to help me easily type my essay.

Structure is the most important thing in an essay. You can be a great writer, but without a format you'd get a C. Use the following as a guide:

As for a topic war, your most obvious choice would be one of the Crusades. Take your pick.

Eighth grade Algebra l Honors test, shouldn't be too hard.

Ex: 2/3(2 over three).
Ex: 4(2sq) Means 4 to the second power.

Simplify, posit. exponents

1)(2/3R)(3sq) (27R) (5S)(2sq) (1/2s(4sq))(3sq)

2)(-2mx(-3sq))(-4sq)
8M(-5sq)X(0sq)


M(2sq)np(2sq) + mn(3sq)p(2sq)-4m(4sq)n - Find the degree

Simplify:
5n(2sq) (n-6) -2n(3n(2sq)+n-6)+7(n(2sq)-3)

Use Foil.
(6x+4y)(2sq)

Answer:

A square has sides of length (3x-1)feet. Write an expression that represents the area of the square.


If F(x)=x(2sq)+5x and g(x) = 2x-x(2sq), find F(a+1) - G(a+1)


The length of a rectangle is 4 cm more than its width. If the length is increased by 8cm and the width is decreased by 4cm, the area will remain unchanged. Find the original dimensions of the rectangle.


Graph the solution set of (x+3)(x+5)+(x+1)(2sq) < 2(x+1)
(The graph looks like this <--------->)


The length of one rectangle is 7m more than the width. The width of a smaller rectangle is 4m less than and the length is 3m more than the width of the larger rectangle. The difference in the areas of the two rectangles is 108m(2sq). FInd the length of the smaller rectangle.

I need help with the DBQ Essay, for European AP History, as a 10th-12th grader, i am a 10th grader. This is the question and the documents: http://www.thecaveonline.com/APEH/dbqmanchester.html

Use Foil.
(6x+4y)(2sq)

6x*6x + 6x*4y + 6x*4y + 4y*4y
36x^2 + 24xy + 24xy + 16y^2
= 36x^2 + 48xy + 16y^2

Answer:

A square has sides of length (3x-1)feet. Write an expression that represents the area of the square.

A= s^2
=(3x - 1)^2
=9x^2 - 6x + 1

If F(x)=x(2sq)+5x and g(x) = 2x-x(2sq), find F(a+1) - G(a+1)

I suppose you mean x+1?

(x+1)^2 + 5(x+1) - 2(x+1) + (x+1)^2
2(x+1)^2 + 3(x+1)
2( x^2 + 2x +1 ) + 3x + 3
2x^2 + 4x + 2 + 3x + 3
2x^2 + 7x + 5

The length of a rectangle is 4 cm more than its width. If the length is increased by 8cm and the width is decreased by 4cm, the area will remain unchanged. Find the original dimensions of the rectangle.

x(x+4) = (x+12)(x-4)
x^2 + 4x = x^2 + 8x - 48
48 = 4x
x = 12

So, 12*16

I would advise to post a picture of the exponent ones, it gets confusing.
You can try the rest. I don't feel like doing them.

Here's a question I'm puzzled at. It's proof by induction.

1+2x+3x^2+...+nx^(n-1) = (1-x^n)/(1-x)^2 - (nx^n)/(1-x)

I think I understand the method, you prove it true for n=1, then assume true for k, then add the k+1 term to the right-hand-side and rearrange it cleverly. If someone can walk me through this one then I'll be grateful.

Edit: I can do the first parts, I'm stuck with subbing the k+1 in place of n, and rearranging it properly.

Physics final. >_<

I basically need to construct a pair of flotations to walk across a pool with. It must cost under $10 and be no more than 2.5m wide per shoe.

Or simply help calculating buoyancy. Thanks.

not a math question but equally hard, Latin translation,

Gaius, quamquam iratissimus erat, nihil tamen dixit quod h&#333;c tempore fratrem reprehendere nol&#275;bat. Statim signum serv&#299;s dedit. Tum ali&#299; ex e&#299;s porcum scind&#275;bant, ali&#299; carnem ad conviv&#257;s portabant. Non omnibus d&#275; porc&#333; datum est: clientibus quidem data sunt pull&#333;rum frustra.

Gaius serv&#333;, “Puer,” inquit, “da fratr&#299; me&#333; quoque frustra pull&#299;! Nol&#299; e&#299; d&#275; porc&#333; d&#257;re!”

Nunc omn&#275;s cibum atque vinum hab&#275;bant. Omn&#275;s cenam laudabant. Etiam client&#275;s quamquam frustra modo hab&#275;bant, un&#257; cum ceter&#299;s clamabant, “Euge! Gaius Cornelius cenam optimam dare solet. Nemo meliorem coquum habet. Nonne coquum ipsum laud&#257;re deb&#275;mus?”

Itaque coquus vocatus ab omnibus laudatus est.

Tandem fercula &#257; serv&#299;s ablata sunt. Simul Gaius serv&#333;s iussit secund&#257;s mens&#257;s in triclinium port&#257;re. Serv&#299;, quamquam, defess&#299; erant, h&#363;c ill&#363;c curr&#275;bant. Uvae, mala, pira in triclinium portata sunt. Passum quoque in mens&#257; positum omnibus est datum.

if anyone knows a substantial amount on the time period.. would they care to put this following information into a singular paragraph for me?

would be much appreciated!!!

WEALTH
Booty: Expand on this, find on Thut III section in Bradley and add some information. Say that much of the “Golden Ages” wealth can be attributed to booty.
Resources: Highlight that resources from captured land was also useful in stabilizing/stimulating the economy. Find some examples. Ie. Grain.
Tribute: In addition, tribute contributed to the wealth. Example.
Wealth led to the ability to beautify, ie building prog. = Maat.
Interests of the ruling class = Amun cult embellishment. Filial duty.
Warrior pharaoh image.
Remember to reinforce why they are important.
