xx+3x+7=6x+18 xx+3x+7-(6x+18)=6x+18-(6x+18) xx-3x-11=0 Factors of -11: 1,-11 -1,11 Doesn't factor evenly, use quadratic

sqrt(XX) - 2x = X - 2X = -X

No 9xx-18x+36 9(xx-2x+4) xx-2x+4 (doesn't factor evenly)

Let x be the smallest number.So,x + (x + 5) = 3x - 32 x + 5 = 3x - 32x - 2x 5 + 3 = 3x - 2x -3 + 38 = xx + 5 = 8 + 5 = 13the smallest number is 8, and the other number is 13.

Doesn't factor evenly, use quadratic -.5xx+2x+10 -.5(xx-4x-20) No factors of -20 add up to -4

It depends. Do you mean 3X as in 3 times X or do you mean 3 subtracted from X? (By the way, roman numerals are always capitalized) If you mean the former, then 3X is 30 which is equal to XXL (L being 50 and XX being the 20 subtracted from it). If you mean the latter, the 3X = 7 which is not equal to XXL or 30.

NOTE: xx can be written as x^2 i.e. x squared 3x^2 + 16x + 5 = 3 x^2 + x + 15x + 5 (Since 16x = x + 15x) = x ( 3x + 1 ) + 5 ( 3x + 1 ) = ( x + 5 ) ( 3x + 1 ) Therefore the factors are ( x + 5 ) and ( 3x + 1 )

If you mean (6x^2)/(2x^2), this problem is easy. (6x^2)/(2x^2) = (6/2) x (XX/XX) (XX is an easy way of writing X^2) 6/2 = 3 XX/XX = 1 3 x 1 = 3 so your answer is 3.

3xx + 2 + xx + 4 = 4xx + 6 = 2(2xx + 3)

IX (9) + XV (15) + XX (20) = XLIV (44)

20000=XX with horizontal bar above the 2X's.

Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.

This is done by using a method called the distributive property. This is actually quite simple if we had x(y+z) we would distribute that xx, and get xy+xz. This is what we will use to solve this problem.If we take 6(5-2x) -4(3x+1) I have made the + sign bold, assuming that this is the symbol there.So next we'd use the distributive property and get 30-12x-12x-4.Now we would combine like terms, and get 26-24x.

x2+xx = 15 Which is the same as: x2+x2 =15 2x2 = 15 x2 = 7.5 x = the square root of 7.5

how do you solve 8+x=x+8

Well in alchemy classic it is 2x Bacteria but that's the only one I have found xx ;)

yes because it is in the 5x 2x 10x and 1x tables xx abbey

x=5 so it's 55+55= 110

No its not true, its just a rumer :P but he is dating Vanessa xx

30.5

true

As l11 are not Roman numerals they cannot meaningfully be added to XX (20) to make any result.

A thousand hope this helps xx
