Answer:

x=+i\sqrt{20}\approx+4.472i

x=-i\sqrt{20}\approx-4.472i

Step-by-step explanation:

Starting from x^2+20=0, we do x^2=-20, which means x=\pm\sqrt{-20}, which can be written as x=\pm\sqrt{(-1)(20)}, which gives us x=\pm\sqrt{(-1)}\sqrt{(20)}, which we know is x=\pm i \sqrt{(20)}, so our solutions are:

x=+i\sqrt{(20)}

x=-i\sqrt{(20)}

Which can be approximated to:

x\approx+4.472i

x\approx-4.472i

ch4aika [34]
<h2> The answer is very simple add the whole numbers then find the LCM of 3 and 4 which is 12 then multiply 3/4 by 3 which will be 9/12 then multiply 2/3 by 4 which will be 9/12 then we add 9/12 + 8/12 which will equal to 5 17/12 which we can reduce and answer will be 6 5/12 spinach.</h2>

There are 21 more days before the first big winter storm and the squirrel collects 12 acorns a day, how far away from her origin
alexandr402 [8]
She has 445 left after the bear ate some so
21 × 12 = 252
252 + 445 = 697 acorns

she should maybe bother the bear so he can't hibernate, or steal his food so he knows what it's like

W = 3x + 7y solve for y
mario62 [17]

Answer:

The value of the equation y=\frac{W-3x}{7}.

Step-by-step explanation:

Consider the provided equation.

W = 3x + 7y

We need to solve the provided equation for y.

Subtract 3x from both side.

W-3x= 3x-3x+ 7y

W-3x=7y

Divide both sides by 7.

\frac{7y}{7}=\frac{W-3x}{7}

y=\frac{W-3x}{7}

Hence, the value of the equation is y=\frac{W-3x}{7}.

Simplify. (-2)-3 -8 - 8 user: simplify. 6x-2
Vinvika [58]
If you would like to simplify <span>(-2)-3 -8 - 8 and 6x - 2, you can do this using the following steps:

</span><span>(-2)-3 -8 - 8 = - 2 - 3 - 8 - 8 = - 5 - 8 - 8 = - 13 - 8 = - 21

6x - 2 = 2 * (3x - 1)

The correct result would be - 21 and </span><span>2 * (3x - 1).</span>
