the answer to (3x^2)(6x^3) divided by 2x^4 can be simplified to 3x3=9, and 6x6x6=216. so 216x9=1944, so then you divide 1944 by 2x^4, which is 2x2x2x2=16, so 1944 divided by 19=$${\frac{{\mathtt{1\,944}}}{{\mathtt{16}}}} = {\mathtt{121.5}}$$

Thank you so much!

it is a variable or unknown so they had to name it

yes i do not to be rude but if u pay attention it gets easier hope it works for u it did for me ask me i will awnser another one if u like

[(2x^4)^3]^2

-----------------------------------------------------------------------------------------------------

Remember, by a property of exponents, (a b)^m =   a^m b^m

Then, applying the exponent "3" across the terms inside the parentheses, we have

(2)³ * (x⁴)³   = (8)(x)¹²

And applying the exponent outside the bracket - (2) - to this, we have

8² * [(x)¹²]² =   64x²⁴ 

-2(u – 8) = -4

---------------------------------------------------------------------------------------------------

So, we want to solve for u........first, divide both sides by -2......we have

u - 8  = 2      add 8 to both sides

u = 10

if (x -5) to the second power + (y + 2)to the second power = 64 what is the radius

---------------------------------------------------------------------------------------------------

So we have (x - 5)² + (y + 2)² = 64

The general equation of a circle is

(x - h)² + (y - k)² = r²      Where the center is (h,k) and r is the radius.

So, in our question, r² = 64

Taking the (positive) square root of both sides, we have

r = 8

Find the two missing fractions.

1/3, 2/12, x/x, x/x, 5/39

--------------------------------------------------------------------------------------------------

OK.....the numerators seem to go 1,2,3,4,5

The denominators are a little trickier.

What did we add to 3 to get 12 ??     ⇒ ⇒  ⇒   9

Then, if we added 9 to 12, we'd get 21.

See if you can finish this, now.........

It is 69/230

Thanks for that answer BluePhoenix912. I gave you a "thumbs up."

If we wanted to leave it in fractional form, we would have

1/2 x 5/8 = 5/16

factor -16t^2+80t+96

----------------------------------------------------------------------------------------------------

OK......let's take out any greatest common factor, first.

This is -16.

So, we have

-16(t² - 5t - 6)

Now, we need two numbers that multiply to the last term inside the parenthesis, (-6) and sum to the coefficient on the "t" term, (-5).

The first two that come to my mind would be -6 and +1. I think that's what we need.

So we have

-16(t - 6)(t + 1)

What is 1.3% of 3,500,000

----------------------------------------------------------------------------------------------------

When we multiply by a percent, we need to "drop" the percent sign and move the decimal two places to the left.

We have 1.3% = .013

New, just multiply this by 3,500,000 to get your answer.

x+3/2=y so i would guess.

Putting this straight into the on-site calculator, we get......... 146225.75

How many inches in 6 yards

----------------------------------------------------------------------------------------------------

There are 36 inches in 1 yard

See if you can take it from there.

I'm afraid I don't understand your question......what "missing" fractions??

What is 20 in scientific notation?

----------------------------------------------------------------------------------------------------------------------------

20 = 20.0

Move the decimal so that only one non-zero digit is to its left.

Thus, we have

2.0      Then, multiply this times 10 raised to a positive exponent indicating the number of places the decimal was moved.  So we have

2.0 x 10 ¹ 

Moving the decimal to the left is indicated by a positive exponent. Moving it to the right results in a negative exponent.

You have to know at least one variable or have some other equation to solve. 

It is impossible to answer your question if there is only one equation to use for two variables.

A circle, or sphere

^{The answer is 0.0066.}

The answer is a circle
