x+7sqrt(x)-18=0  I need urgent help.?

u = SQRT(x)\nThis will make the equation\nu^2 + 7u - 18 = 0\nu = 2\nu = -9 does not give any x real\n\nu = 2 ===> 2 = SQRT(x) ===> x = 4

2x + 28 < with a line under it _ <_   6x\n\nsorry don't know how to add that special character in, but it is only one thing like the +\n between the 28 and 6

I would assume that one of your .01s in column A is something like 0.012.\n\nChange your number  format to General and see what happens.

you loop after I if loop needs to have a concat for  -0-1-2-3-4-5-6- which you never made, you only made one for the Y columns\ni'm don't have java install so i can't check it for sorry.

Sqrt[8]=Sqrt[4x2]=\nSqrt[4]xSqrt[2]=\n2xSqrt[2]=\n2Sqrt[2]

well...after transfering the "+7" in the right of the equal sign and which becomes "-7"(the sign is changed from "+" to "-") we have on the left "2x" and on the right "24-7" which is "17". After this we divide "24" at "2" which comes from the "2x" in order to find "x" and the result is that "x=8,5" or "x equals 8,5".

7t+15 > 3t-13\n4t > -28\nt > -7

(x-7)(x-5)\nso x= +7, or +5

just like the person above (bree) says but you can further reduce the 18. \n\nx= 3c sqrt(2)

2√72 + √32 - 4√18\n= 2(√8*√9) + (√8*√4) - 4 (√2*√9)\n= (2*3)√8 + 2√8 - (4*3)√2\n= 6(√2*√4) + 2(√2*√4) - 12√2\n= (6*2)√2 + (2*2)√2 - 12√2\n= 12√2 + 4√2 - 12√2\n= 4√2\n\nHope this helps.

you must include x=0.

Here's how to work it out:\n\n(Sorry, because I can't use special symbols, I'm using _/ for the square root symbol and <= for the less than or equal to symbol.)\n\n_/3x + 6 + 4 <= 7\n_/3x + 10 <= 7\n3x + 10 <= 7 x 7\n3x + 10 <= 49\n3x + 10 - 10 <= 49 - 10\n3x <= 39\n3x/3 <= 39/3\nx <= 13

The answer, before simplification, is sqrt(-8). There is no need to panic, as some of the other answerers did. This simplifies easily to\n\n2 * i * sqrt(2)

Just put each number in for x and see what the answer is.  Example : -11/2 + 75 = -5.5 + 75 = $69.50 a unit.

Subract the two terms on the left giving:\n-2t < 16\n\nAdd 2t to both sides giving\n0 < 16 + 2t\n\nSubtract 16 from both sides\n\n-16 < 2t\n\nDivide both sides by 2\n\n-8 < t

yes. take out an x \nyou answer should be x(x+3)
