Does it look like this: \frac{ \sqrt{-4} }{(3+i)-(2+3i)} =  \frac{-2i}{1-2i} or \frac{2i}{2i-1}

Do you need the others?

Answer:

\frac{-4+2i}{5}  

Step-by-step explanation:

\frac{\sqrt{-4}}{(3+i)-(2+3i)}

simplify the denominator

\frac{\sqrt{-4}}{1-2i}

square root (-4) is +2i , because the value of square root (-1) is 'i'

\frac{+2i}{1-2i}                    

multiply top and bottom by its conjugate 1+2i

\frac{2i(1+2i)}{(1-2i)(1+2i)}  

\frac{2i+4i^2}{1+2i-2i-4i^2}  

The value of i^2 =-1

\frac{2i+4(-1)}{1+2i-2i-4(-1)}  

\frac{2i-4}{5}  

\frac{-4+2i}{5}

The length is 7.2 feet.

Step-by-step explanation:

It is a ratio of 10:18. Therefore you can simplify the ratio to 18/10 or 1.8. This then becomes 4 (width) times 1.8, or 7.2 feet. :)
