<em>Answer: </em>

<em>Elena's running speed is 5 miles/hour </em>

<em>Explanation: </em>

<em>The speed is defined as the covered distance per unit time </em>

<em>In the problem, we have: </em>

<em>The distance covered is the length (circumference) of the circular track which is given as  of a mile. </em>

<em>We are also given that she completes each lap (she completes  of a mile) in  of an hour </em>

<em> </em>

<em>To get her speed, we will divide the distance covered by the time taken to cover this distance </em>

<em>This is done as follows: </em>

<em>speed =  miles/hour </em>

<em>This means that: </em>

<em>Elena can run 5 miles each hour</em>

What is the solution of the equation over the complex numbers
denis-greek [22]

<u>Answer:</u>

2i\sqrt{3}

-2i\sqrt{3}

<u>Step-by-step explanation:</u>

x^2 + 12

First set the equation to 0

x^2 + 12

x^2 + 12 = 0

Second, get the 12 on the right side of the equal sign by adding a -12 to each side

x^2 + 12 = 0

x^2 + 12 + (-12) = 0 -12

x^2 = -12

Square root both sides of the equal sign.

x^2 = -12

\sqrt{x^2} = \sqrt{-12}

Take the square root on left sides of the equal sign.

\sqrt{x^2} = \sqrt{-12}

x = \sqrt{-12}

Take the square root on the right side of the equal sign. Remember \sqrt{-1} = i

x = \sqrt{-12}

x = \sqrt{4}*\sqrt{-1}\sqrt{3}}

x = 2i\sqrt{3}

<u>AND</u>

x = -2i\sqrt{3}
