What is the value of x when you have to find the geometric mean of x-3 and x 4 is x?

I will assume that the gap between the X and the 4 is due to this website's inability to include +'s so I will use a +.
geometric mean of (x-3) and (x+4) is x
x^2=(x-3)(x+4)
x^2=x^2+x-12
0=x-12
x=12

What I helps you to find the area under the curve y x3 4x - 3.6?
"integration"
How many cubic yards of concrete is in a hole 3'x3'x3'?
One cubic yard.
What cubes have the same volume and surface area?
Congruent ones. A cube of side x has a volume of x3. Any other cube, of volume x3 must have sides of length x and so the two cubes must be congruent.
How many square meter in a 7feet by 3 feet room?
21 square feet (7'x3') = 1.95 square meters.
What size cube has a surface area equal in number to its volume?
Suppose the cube has edges of length x. Then the area of each face (side) is x2. There are six faces so the total surface area is 6x2. The volume of the cube is x3. So 6x2 = x3 DIviding both sides by x2 gives x = 6.
X3 64 343?
The math problem X3 times 64/334 equals 4/7. Getting this answer you will first have to find the value of X.
What does x3 mean?
x3 can mean a lot of things, for example:In math is can mean: the variable x equals 3.In BMW sportcars: X3 is a model of car with a meaning often known only to the car company.On mechanical drawings: x3 can mean times 3
What is skewness and How would you find it in a non symmetrical distribution?
If a random variable X has mean value m, and standard deviation s, then Skewness = E{[(x - m)/s]3} which can be simplified to skewness = [E(X3) - 3ms2 - m3]/s3 and for discrete X, E(X3) = sum of x3*Prob(X = x) where the summation is over all possible values of x. While for continuous X, E(X3) = integral of x3*f(x) where the integral is over the domain of X.
What is x2 times x3?
If x2 and x3 are meant to represent x2 and x3, then x2 times x3 = x5 You find the product of exponent variables by adding the exponents.
X 3-1 x-1?
X3-1x-1 is known as a math problem. All you have to do is work to find what the value of X is.
What is the Kelly Blue Book value for a used BMW X3?
The value of the BMW X3 depends on your location, year, milage, and peripherals. But for a 2009 BMW X3 with 50,000 miles that is in good, not excellent, shape, and all the basic options is worth $26,360.
What is x3 plus 125?
It is a cubic polynomial in x and its value depends on the value of x.
How to find the cube of an area?
x3
The formula of mean median mode?
If you have n observations for a variable X: x1, x2, x3, ... xn thenMean = (x1 + x2 + x3 + ... + xn)/nTo find the median, put the Xs in order and find the middle one. If n is odd then it is the value of the X in the (n+1)/2 position. If n is even, then it is half the sum of the Xs in the n+2 and n/2+1 positions.There is no formula for the mode. It is simply the value that is observed most often.
What does the word indicate mean in math?
A mathematical mean is the average of a group of numbers. To find it, you add all of the numbers you're being asked to find the mean for and then divide by the number of numbers you added. In other words, the average.* * * * *There are other means which are useful in other circumstances. The two common ones are the geometric mean and the harmonic mean.The geometric mean, for a group of n positive numbers is the nth root of the product of the numbers.So, G(4,6,9) = cuberoot(4*6*9) =cuberoot(216) = 6The geometric mean is useful with numbers that are used as multipliers, such as growth rates.The harmonic mean of n numbers x1, x2, x3 ,... xn is the number H such thatn/H = 1/x1 + 1/x2 + 1/x3 + ... + 1/xnThe harmonic mean is useful when the average of rates is desired. For example, if you travel k miles at x mph and another k miles at y mph, your average speed would be H(x,y).Mean is another name for 'average'. Here you add up the scores and divide this new number by how many scores there are.in notation this is (Sigma (xf-xi)) / x
How do you find the greatest common factor of variables?
Choose the lowest of the exponents. The GCF of x3 and x5 is x3
If x3-1 equals 11 What is the value of x?
x=4.
