How do you factor 100V square minus 25W square?

100 V2 - 25 W2 = (10V + 5W) (10V - 5W)Another way to show it:100 V2 - 25 W2 = 25 (4 V2 - W2) = 25 (2V - W) (2V + W)


What is w to the second power divided by 3w to the second power?

w2/(3w)2 = w2/9w2 = w2-2/9 = w0/9 = 1/9 or w2/3w2 = 1/3


How do you factor w2 18w 81?

(w + 9)(w + 9)


The length of a rectangle is 6 meters more than its width If the area is 135 square meters what is its width?

w x w + 6 = 135 w2 + 6w - 135 =0 Ie (w - 9)(w + 15) = 0 width = 9m (length = 15m)


If the area of a rectangle is 18 square inches and the length of the rectangle is twice it's width what is the length and width of the rectangle?

A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.

How do you solve w2 plus 49 equals 0?

If by w2 you mean "w squared", then it cannot be done. BECAUSE w2 + 49 = 0 w2 +49 - 49 = 0 - 49 w2 = -49 w2 means a number multiplied by itself. Any number multplied by itself will result in a POSITIVE number. positive x positive = positive negative x negative = negatve

Xsquared - v equals wsquared what is X how did you work this out?

It is not possible to solve for a value of X since there are three unknowns, X, v and W and only one equation. All that can be done is to make x the subject of the equation - that is, to express X in terms of the other two variables. X2 - v = W2 X2 = W2 + v X = +/- sqrt(W2 + v)


I lost my original w2. Can you file a return with a reprint W2?

It does not matter if you file with your original W2 or not. As long as you have a copy of the W2, that is all that is needed. If you file online, you do not even need to send your W2 in.

Find the maximum area of a rectangle inscribed in a circle of radius 12 in?

The length and width of the rectangle (and thus it's area) will be defined by the circle. Specifically, the diagonal of that rectangle will always be equal to the diameter of the circle. To find the maximum area then, one can simply define the rectangle with that relationship, take the derivative of that function, and find out where that comes to a value of zero. The area will be peaked at that point: a = lw d2 = l2 + w2 ∴ l = (d2 - w2)1/2 Remember that the radius is 12, so the diameter is 24, and things can be simplified by plugging that into the equation at this point: l = (576 - w2)1/2 ∴ a = (576 - w2)1/2 w The next step is to take this equation for area, and find it's rate of change with respect to width: ∴ da/dw = (576 - w2)1/2 + 1/2 * (576 - w2)-1/2 * -2w * w ∴ da/dw = (576 - w2)1/2 - (576 - w2)-1/2 * w2 Now let that value equal zero: 0 = (576 - w2)1/2 - (576 - w2)-1/2 * w2 ∴ (576 - w2)1/2 = (576 - w2)-1/2 * w2 ∴ 576 - w2 = w2 ∴ w2 = 576 / 2 ∴ w2 = 288 ∴ w ≈ 16.97 And one can work out the corresponding height: d2 = l2 + w2 ∴ 242 = l2 + 288 ∴ l2 = 576 - 288 ∴ l2 = 288 ∴ l ≈ 16.97 Meaning that the optimum rectangle is a perfect square. To be completely thorough, it should be confirmed that the area found was a maximum and not a minimum. This can be done easily enough by taking a slightly lesser width and a slightly greater width, and seeing how their areas compare: a = (576 - w2)1/2 w Let w = 16 ∴ a = (576 - (16)2)1/2 * 16 ∴ a = 3201/2 * 16 ∴ a = 51/2 * 128 ∴ a ≈ 286.22 Let w = 18 a = (576 - 182)1/2 * 18 ∴ a = 2521/2 * 18 ∴ a = 71/2 * 108 ∴ a ≈ 285.74 Both of these values are less than the area surrounded by the square, so the square's area is indeed a maximum and not a minimum.
