The prime factorization of a number is all the prime numbers that multiply to make it.
So to find the prime factorization of 98:
98/2=49
(2 is a prime number; set it aside)
49/7=7
7 is also a prime number, and it appears twice
so the prime factorization of 49 would be
2*7*7
=2*7^2

Subtracting a negative number is like adding it's opposite.
So for -5 minus -14, it would be
-5 plus 14
so that would be
14-5
=9

Subtract 2Pi*r^2 from both sides of the equation. then 2Pir*h= 1435-2Pir^2 next divide both sides by 2Pir giving h= (1435-2Pir^2)/2Pir . substitute 4.87 for r and the calculator value for Pi and you can get a numerical value for h.

sin-1 means{ the angle whose sin is): it is sometimes called arcsin. on the calculator if you press 2nd sin and enter .5 you will see an answer of 30 because sin 30 degrees = .5, assuming the calculator is in degree mode

In a 30, 60, 90 triangle, The sides are in the ratio 1, (sq. rt. of 3), 2, respectively.If the side opposite 30 degree angle =2, then the side opposite the 90 degree angle would =4. What is the length of the side opposite the 60 degree angle?

If you're trying to solve for r, I think I have an answer for you First, to simplify the problem, we must divide each side by -25. -3125 / -25 = 125. -25 * r^3 / -25 = r^3. Therefore, 125 = r^3. Lets simplify further. Log3 125 = r. Since log3 125 also equals 5 (because 5^3 = 125), r = 5.

Let's put together the first and the second equations multiplying the second of them by 2 in advance: we get 5z + 6x = 4.
Now, consider this equation and the third one. Let's eliminate one of the variables,for example, z. We'll achieve that by multiplying the new equation by 3, the third original one by -5. By putting them together, arrive at the simplest equation 13x = - 52 => x = 4. By inserting it in the third equation we find z = -4, inserting x into the second original we finally get y = 6.

-18+8-8/4*4
You have to do the multiplication and division first.
-8/4=-2 x4= -8
-8 +8 = 0
You have -18 left
Essentially you can work this problem backwords!

The square roots have indentical indices. So, one may take the square root of 300 (the product of 60 and 5) . The answer can be rounded to 17.32.

Acabo de darme cuenta de que lo que he dicho antes hizo absoluta no tiene sentido, y lo siento! Hahaha, pero sí, si tengo más preguntas me aseguraré de preguntarle, es difícil escribir en Inglés, pero le ayuda a entrar en la universidad y de cosas (: Así que gracias de nuevo voy a publicar a menudo! con preguntas, porque yo voy a llevar las finanzas personales y para mí es duro.

3(2x-5)=2(3x-2)
Simple and best practice solution for 3(2x-5)=2(3x-2) equation.
Equation:
Solution for 3(2x-5)=2(3x-2) equation:
Simplifying
3(2x + -5) = 2(3x + -2)
Reorder the terms:
3(-5 + 2x) = 2(3x + -2)
(-5 * 3 + 2x * 3) = 2(3x + -2)
(-15 + 6x) = 2(3x + -2)
Reorder the terms:
-15 + 6x = 2(-2 + 3x)
-15 + 6x = (-2 * 2 + 3x * 2)
-15 + 6x = (-4 + 6x)
Add '-6x' to each side of the equation.
-15 + 6x + -6x = -4 + 6x + -6x
Combine like terms: 6x + -6x = 0
-15 + 0 = -4 + 6x + -6x
-15 = -4 + 6x + -6x
Combine like terms: 6x + -6x = 0
-15 = -4 + 0
-15 = -4
Solving
-15 = -4
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
I used translate, so I hope you can understand (:

The cube root of 20000 is 27 and a bit.
So if you look at all th numbers from 1cubed to 27cubed and choose the ones that are also squared.
It wouldn't take all that long to do so long as you have a calculator.

These two solutions are absolutely equivalent. The only difference was that I had passed to a homogeneous equation, while you preferred to transform it algebraicly. Just matter of your taste to choose the way of solution. Also, the final result of my calculation is identical to yours. I just didn't pay much significance to rationalizing that fraction.

Yes it is the same but your answer is not fully factorised.
(6x-2)(6x-2)= 2(3x-1) * 2(3x-1) = 4(3x-1)

for two consecutive integers, the sum of the smaller and twice the larger is 29. Find the smaller integer.
Let the numbers be x-1 and x
x-1 +2*(x) = 29
x - 1 + 2x = 29
3x - 1 = 29
3x = 30
x=10
The numbers are 9 and 10
The little one is 9
You could have let the numbers be x and x+1 if you wanted. the answer would be the same.
