what is the % notation of 6.3 (answer)

630%.  Remember, to put it in percent notation, you multiply by 100.  Or, move the decimal two spaces to the left.  Kudos!

2x^2+4x-240 (answer)

Hello Lord, Well the first thing I'll factor out is 2.  Now it's 2(X2 + 2x - 120) Now I'm looking for two numbers that have a product of 120 and a DIFFERENCE of 2.  I say difference because remember, these two numbers are going to have to multiply to -120. ...

Multiply (2x+4)^2. (answer)

Hey there.  Since you are squaring it, you multiply it by itself.  Thus it's: (2x + 4)(2x + 4) You need to FOIL it.  You know, First, Outside, Inside, Last: 4x2 + 8x + 8x + 16. Then combine like terms: 4x2 + 16x + 16. Shake a leg...

How many whole numbers round to 1000? (answer)

Well that depends.  If you're rounding to the nearest ten, it would be ten:  (995 - 1004).  If you were rounding to the nearest hundred, there would be a hundred, to the nearest 1000 there would be a thousand.

Can anyone solve this equation (answer)

Jimmy, Piece of cake!  First of all, divide each side of the equation by the common denominator of 2.  It makes it easier.  Now you have:  X2 -4x = 12.  Now you'll either factor it or use the quadratic formula.  Either way, you need to set it to zero.  So...

Using the quadratic formula what does x = (answer)

Jimmy, The number of answers in infinite, as the value of X will depend on Y.  As an example, let's say Y were equal to 7 (just because).  If Y were equal to 7, I would therefore have: 7 = 4x2 + 6x - 2.  Now remember, the quadratic formula only works if the equation...

how do i anser these (answer)

WAIT!!!  Tamara and Venkata are wrong.  Remember, division does not come before multiplication.  They are done at the same time.  The way you decide which to do first is by going from left to right.  If you have an equation written like this:  [75รท5(4-1)]x9 Then...

Ax + By= Cz (answer)

So this is saying A to the X plus B to the y equals C to the z.  A, B, C, x, y, and z are all positive integers and and the latter three are all greater than 2.  Am I missing something here?  There's an endless number of answers.  Here's one, and it's a simple one:  Say...

how many candles and soap do i need to sell? (answer)

Okay, I'll answer this in parts. A.  C + 2S > 200 This is assuming that c is the number of candles that are sold at the fundraiser.  Remember, the profit on C and S is a dollar and two dollars, respectively.  Think about it;  1.75 - .75 and 3.25 - 1.25.  Since...

find the distance between the points (-2,5) and (12,-1) (answer)

Dear Louis, You can figure out the precise distance between these two points by using what you know about right triangles:  that the sum of the squares of the legs equals the square of the hypotenuse. Here's how.  First, plot both of these points (-2, 5) and (12, -1) on a piece...

Trigonometry (answer)

Hello. Kevin S. In Seneca did an excellent job in figuring out that this equation can be factored and set equal to zero.  It can be factored into two binomials:  (4Sin(x) - 3)(Sin(x) - 1) = 0.  From here, it's a piece of cake.  You just set the factors to zero. ...
