If a storm window has an area of 400 square inches what is the equation to find the dimensions when the window is 12 inches higher than it is wide x represents height?

area = width times height
x = height
x-12 = width
x (x-12) = x^2 - 12X = 400
x^2 - 12X - 400 = 0
solve for x using quadratic formula
X = (12 + SQRT(144 + 1600)) divided by 2
x = 26.88 = height
width = x -12 = 14.88

If a storm window has an area of 640 square inches what is the equation to find the dimensions when the window is 20 inches higher than it is wide?
H = W + 20; H x W = 640 ie W x (W + 20) = 640 ie W^2 + 20W - 640 = 0 This does not have a solution in integers, a close approximation is 17.2 x 37.2
Can centroid be negative?
A centroid is a location. A location cannot be positive nor negative! One or both coordinates can be negative. Or more coordinates in higher dimensions.
The volume of a box that's nine centimeters long six centimeters wide and three centimeters high is?
To find the volume of a rectangular solid (just like your box), you multiply the dimensions of Length, Width and Height. For your question: Volume = Length * Width * Height Volume = (9 cm) * (6 cm) * (3 cm) Volume = 162 cm3 To take this to a slightly higher level, you can give your answer in other units, recalling that 1 mL = 1 cm3, and you get the Volume = 162 mL
What are higher dimensions and what do they look like?
A higher dimension is exactly what it sounds like: a dimension that is different (higher) from length, width, and depth. Our world is in three dimensions, and a higher dimensional universe would have four or mroe dimensions.
How does the solution to an inequality differ from the solution to an equation?
The solution to an inequality generally is a region with one more dimension. If the inequality/equation is of the form x < a or x = a then the solution to the inequality is the 1 dimensional line segment while the solution to the equality is a point which has no dimensions. If the inequality/equation is in 2 dimensions, the solution to the inequality is an area whereas the solution to the equality is a 1-d line or curve. And so on, in higher dimensional spaces.
How does the height a boucny ball is dropped from effect the height it bounces to?
The higher the height the ball is dropped from, the higher the height it will bounce to.

What period of art was influenced by the notion of higher dimensions?
Cubism
Which is true for a counterbalance lift truck the higher the lift height?
Height does not affect capacity.
What is dimension in geometry?
In geometry, a dimension refers to the number of coordinates needed to specify the position of a point in space. In two-dimensional geometry (such as the coordinate plane), only two coordinates (x and y) are needed. In three-dimensional geometry (such as 3D space), three coordinates (x, y, and z) are needed. Higher dimensions refer to spaces with more coordinates, although it is difficult to visualize dimensions beyond three.
How do you rewrite a linear equation?
The answer depends on what form the equation is in and what form you want it in. The standard form is ax + by +c = 0 where x and y are variables and a, b and c are constants. There are also the 1-d equivalent: ax + b = 0 and 3-d equivalent: ax + by + cz + d = 0 and, equivalent equations in spaces with higher dimensions.
Why does grass affect the bounce height of a ball?
the higher the grass the higher the bounce.

Why you can fill a bucket from a downstairs tap quicker than from an upstairs tap?
You can do this because it takes more pressure from the pipe to flow water to the upstairs tap than the amount of pressure it takes to flow water to the downstairs tap. This is clear in Bernoulli's Equation: The fancy-looking p (pronounced rho) in the first two terms represents the density of the liquid, v represents the velocity in which the fluid is traveling, g is the acceleration due to gravity (appx. 9.8m/s^2), and z is the difference in height traveled by the fluid, the final P represents the atmospheric pressure (101.3 kPa). As you can see, as the value of variable z decreases, it allows for the only other variable, v, to increase. This explains why, at a higher elevation and a constant force applied to the fluid, water will flow faster at a lower height than a higher point. EDIT: It won't let me add an image for some odd reason, search Bernoulli's Principle and look for the phrase, "By multiplying with the fluid density", and reference the equation underneath for a more complete understanding of what I just said.
