Solve for x:
sqrt(x^2) = 6

Raise both sides to the power of two:
x^2 = 36

Take the square root of both sides:

 x = 6       or        x = -6

you can't multiply by variable!

what if x=0?

Answer: (x+8)(x+8)

We can say this as...

What two numbers multiply to +64 and add to +16?

We can find that 8 and 8 add to 16 and multiply to 64.

Now, since x^2 is also 1x^2, this makes it easy. It is simply (x+8)(x+8).

You are very welcome!

I don't want to tell you the full answer, but I'll start you off.

Multiply both sides by x and get \(\sqrt{1-4x^2}-1 \geq -4x\).

To get rid of the radical, we can move all radical signs to the left and non-radicals to the right.

This is what we'll do here.

\(\sqrt{1-4x^2} \geq -4x+1\).

Now square both sides, and then you probably know what to do from there.

You are very welcome!

Find two integers whose sum is -9 and product is -10?

- 10 + 1 = - 9     and     - 10 x +1 = - 10

factor  x^2 + 16 x + 64 = 0

(x + 8)^2 = 0,  (x + 8)(x + 8) =0

x = - 8,    x = - 8

Solve for x:
x^2 + 27 = 0

Subtract 27 from both sides:
x^2 = -27

Take the square root of both sides:

x = 3 i sqrt(3)      or        x = -3 i sqrt(3)

Solve for x:
x^2 - 5 x - 8 = 0

Add 8 to both sides:
x^2 - 5 x = 8

Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 57/4

Write the left hand side as a square:
(x - 5/2)^2 = 57/4

Take the square root of both sides:
x - 5/2 = sqrt(57)/2 or x - 5/2 = -sqrt(57)/2

Add 5/2 to both sides:
x = 5/2 + sqrt(57)/2 or x - 5/2 = -sqrt(57)/2

Add 5/2 to both sides:
 
 x = 5/2 + sqrt(57)/2       or          x = 5/2 - sqrt(57)/2

Thank you very much guys for help!

thank you!!!

If the rate is 0.1GB/min for that half, it has taken

0,.GB/(0.1GB/min) = 5 min.

If the download speed (somehow) increased to infinity after that, it would only have taken 5 min to download.

But since a download speed of infinity is impossible, it will definitely take more than 5 mins (though we don't know the speed afterwards)

So the game download time is >5min. :)

15x^2 and 12x are both divisible by 3x.

So,

3x(5x - 4)

For Matrix Multiplication, you have to sure the matrix sizes are compatible. This means when the dimensions (rows x columns) are put side by side, the inner numbers match. The new matrix takes the size of the outer numbers.

For BD, B has dimensions (2 x 2) and D has dimensions (2 x 1)

The inner numbers are (2 x 2) and (2 x 1) which means the matrix multiplication will work.

The size of the product matrix will be the outer numbers,  (2 x 2) x (2 x 1) = (2 x 1).

Good luck with the rest :)

25 is what percent of 29

25 ist wie viel Prozent von 29?

Hello Guest!

\(W=\frac{G\times p}{100\%}\\ p=\frac{W\times 100\%}{G}\)

percentage W=25

basic value  G=29

\(p=\frac{25\times 100\%}{29}\)

\(p=86.2068965517\ \%\)

25 is 86.207 percent of 29.

nope. 

Do you understand?

Thank You!

Yes the question implies integers but integers can be negative.

I assume you are right but I was demonstrating the need for precise language and instructions when dealing with mathematics.
