Rewrite the square-root expression as an imaginary number: sqrt of -64<br><br> is it 8i?

IceJOKER [234]

The answer is 8i.

i = √(-1)

√(-64) = √((-1) * 64)
= √(-1) * √64
= i * √8²
= i * 8
= 8i

Answer:

Step-by-step explanation:

Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.

x + 2x + 5 + 6x - 17 + 3x + 2 becomes

12x - 10

How do you solve each system by graphing

abruzzese [7]

See the attached graph

<h2>Explanation:</h2>

Hello! Remember to write complete questions in order to get good and exact answers. Here you don't provide any system so I couldn't help you in an exact way, but in a general manner. When solving systems by graphing we just need to find the points of intersection of the graphs of the functions that built up the system.

Suppose you have the following system of linear equation:

$\left\{ \begin{array}{c}y=2x+3\\3y=8x+27\end{array}\right.$

yBy using graphing tools, we get the graph shown below. As you can see, the point of intersection of both lines is $(-9,-15)$
