Factor the expression over the complex numbers.<br><br><img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B18" id="TexFormula1

AleksAgata [21]

Here we are given the expression:

$x^{2}+18$

Now let us equate it to zero to find x first,

$x^{2}+18=0$

Now subtracting 18 from the other side,

$x^{2}=-18$

taking square root on both sides,

So we will get two values of x as ,

$x=3\sqrt{-2}$

$x=-3\sqrt{-2}$

Now we can write square root -1 as i,

So our factors become,

$x=3i\sqrt{2}$

$x=-3i\sqrt{2}$

Answer:

The final factored form becomes,

$(x+3i\sqrt{2})(x-3i\sqrt{2})$

Answer:

Step-by-step explanation:

The sum of the interior angles of a square = 360° ( 4 right angles )

The sum of the interior angles of a triangle = 180°

Then sum of interior angles of the figure is

sum = 180° + 180° + 360° = 720° → C

What is 87 24 over 25 as a decimal

erastova [34]

8724/25 = 348.96
When you say "over" that means that it has to be divided that short subtraction sign that separates the numerator and the denominator and also means divide so I believe that if you divide you can find the decimal.
