\frac{10}{ - 8 - 6i}   \times  \frac{ - 8 + 6i}{ - 8 + 6i} =  \frac{ - 80 - 60i}{( - 8 + 6i)( - 8 - 6i)}  \\  =  \frac{ - 80 - 60i}{ - 64 - 36 {i}^{2} }  =  \frac{ - 80 - 60i}{ - 64 + 36}  \\  =  \frac{ - 20 - 15i}{ - 16 + 9}  =  \frac{ - 20 - 15i}{ - 7}

Jermaine has just painted a large mural. It is 8 1/2 feet wide. The wall he wants to place it on is 11 3/4 feet wide. About how
PolarNik [594]
First turn 1/2 to 2/4 so you have a common denominator.
Next turn the mixed numbers into improper fractions:
11 3/4 --> 47/4 and 8 2/4 --> 34/4
Subtract:
47/4 - 34/4 = 13/4
Divide:
13/4 = 3.25
3.25/2 --> 1.625 or 1 5/8
Therefore, he will have to place it 1 5/8 feet from each side

Hope this helps!

Urgent!!!!?
ExtremeBDS [4]

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

x^2=4^2+4^2

x^2=16+16

x^2=32

We take positive square root to obtain

x=\sqrt{32}

x=4\sqrt{2}

x=5.66ft

Rounding to the nearest feet we have x=6ft
