The magnitude of -1-5i is √26.
<h3>What is the magnitude of -1-5i ?</h3>
Given the complex expression; -1 - 5i
To find the magnitude, we use the formula;
| a+bi | = √[ a² + b² ]
| a+bi | = √[ a² + b² ]
| -1-5i | = √[ (-1)² + (-5)² ]
| -1-5i | = √[ 1 + 25 ]
| -1-5i | = √26
Therefore, the magnitude of -1-5i is √26.

If you know the rugs sell for 8$ per square foot and the total spend was $432. You divide 432 by 8 to find the total number of square foot of the rug. Which is 54. To find total square foot you find the area. So the area of a rectangle is L*W. So 54 = 9*width. So just divide 54 by 9 and you get the width of the rug. The width is 6 foot. Now you check. A nine by 6 rugs square foot is 54. and then times by 8 and you get 432 total. So you know the rug is 6 foot wide. :)
