A cube can be negative, so the sum of two pairs of cubes can also be negative.  There is no smallest.

Look for some math help live chatrooms.  Do you have anyone's phone number from school who could help?  Don't sweat it too much.  You can just divide as with any other numbers just remember to put the same number of decimal places in your answer that you began with.  Look at the examples in your textbook.  Good luck.

Q = 25000 - 5000p\nSubtract 25000 from each side\nQ - 25000 = -5000p\nDivide everything by -5000\n(Q-25000)/-5000 = p\nAnswer: p = (25000-p)/5000\nor you could write it as p = 5 - (p/5000)

try sosmath.com  they helped me before. if they don't have the answer you are looking for they have a list of links to tons of other math sites.  \n\nand there probably is someone on your campus that can help as well.  One on one help is always best...\n\nGood luck!

With just ! (Factorial), +, -, * and /, it is impossible to get 150 using only 3 5s without the x^2 (Squared) operation (Which means x*x, in case you are in Fifth Grade), or using a '^2' as you say. If you say there is an alternate way, and there really is, then I give up and admit defeat. (I'm sure most others do.) If you are so sure, why don't you post the answer yourself?

you can write \nP=d product((x-a_i)^k_i)) poduct((x-b_j)^2 + c_j^2)\n Then I give you 3 hints:\n1) d must be positive\n2) all k_i are even numbers\n3) use the formula (a^2+b^2)(c^2+d^2) =\n= (ac-bd)^2 + (ad+bc)^2

y= -(2/3)x^2 + (2/3)x + 4\n\n\n(P): y = ax^2 + bx + c\n\nPoints (0;4)  (-2;0)  (3;0) are element of (P)\n-->  4 = 0a + 0b + c --> c = 4\n0 = 4a - 2b + c\n0 = 9a + 3b + c\n\n--> 5a + 5b = 0 --> b = -a\n--> 4a + 2a + 4 = 0 --> a = -2/3,  b=2/3

first u add -2 to both sides of the inequality.\n-x>5\n\nthen divide both sides by -1 to get x by itself\nx>-5\n\nthe key is to get x by itself, and remember that anything u do to one side of the inequality do to the other.\n\nBtw, the person above me had the answer x>-4 until like a week ago. i think they looked of my answer, making them a cheater. but i don't care, that just means I'm smarter than them. ha ha ha.\n\nnext task, WORLD DOMINATION! mwahaha!

Yes. These are intriguing geometry problems. What is YOUR question? Be specific. Post ONE question and be specific about where you are stuck. Right now, this just looks like you want someone to DO your homework for you. But you wouldn't cheat on your homework like that, would you?\n\nHere's a hint -- supplemental angles add up to 180\n\nFor example, if one angle is 60 degrees, its supplement is 120

1. Square everything in the first set of inequalities.\n\nIf 4 < sqrt(x) < 9, then 4^2 < [sqrt(x)]^2 < 9^2\n\nor, 16 < x < 81.\n\nAs a test, let's choose x = 64. I picked it because it has an easy square root.\n\nIf x = 64 (and note that 16 < 64 < 81), then sqrt(x) = 8, which is greater than 4 and less than 9.\n\n2. If the total cost of x apples is b cents, then the cost of 1 apple is b/x cents. x * b/x = b, which is indeed the cost of x apples according to the problem.\n\nIf 1 apple costs b/x cents, then y apples cost yb/x cents.\n\nAs a test, suppose that 5 apples cost 20 cents. (That is, x = 5, b = 20).  In this case, 1 apple costs 4 cents.\n\nHow much are 6 apples (Let's let y = 6). 6 apples would cost 24 cents.\n\nNow, what is yb/x?\n\n6*20/5 = 120/5 = 24.\n\nIn this case, it checks out. (It will for all cases, but one case doesn't actually prove that it works. It really only justifies it. But it is right :D)

7p-2(3+4p)=12p-(p+4)\n\nfirstly, order of operations, use the distributive property\n\n7p+(-6)+(-8p)=12p+(-p)+(-4)\n\nsimplify, combine like terms\n\n-p+(-6)=11p+(-4) add p and 4 to both sides\n\n-2=12p\n\ndivide by 12,\n\np= (-1/6)

firt you work the problem in the parentheses. that would be (2*-5)+ 4. that would make it -10+4. that equals -6. then you take that and multiply it by -5. that gives you a positive 30

this is probably not a perfect answer but this site may give you some clues.\n\nhttp://www.gomath.com/Questions/question.php?question=4751\n\naltrnatively type 'prove v*v = 2gr*r/s+v0*v0-2gr' into a search engine and see what comes up.
