Answer:

#3×|x-9|=0

|x-9|=0

X-9=0

X=9

# |2x-9|-4=2

|2x-9|=2+4

|2x-9|=6

2x-9=6

2x=9=-6

X=15/2

X=3/2

1 to x power =3/2 or

2 to x power =15/2

Find the quotient and express it in the simplest form

pychu [463]

2i(4+5i)(4-5i) =82i
4+i nothing more can be done it is at simplest form

so $\frac{82i}{4+i}$ = $\frac{82}{17} + \frac{328}{17} i$

so your answer is $\frac{82}{17} + \frac{328}{17} i$

Donte simplified the expression below.

sergij07 [2.7K]

The answer is: [A]: He did not apply the distributive property correctly for 4(1 + 3i) .
_____________________________________________
Explanation:
______________________
Note the distributive property of multiplication:
_____________________________
a*(b+c) = ab + ac.
____________________________
As such: 4*(1 + 3i) = (4*1) + (4*3i) = 4 + 12i ;
_____________________________________
Instead, Donte somehow incorrectly calculated:
_____________________________________
4*(1 + 3i) = (4*1) + 3i = 4 + 31; (and did the rest of the problem correctly);

Note: - (8 - 5i) = -8 + 5i (done correctly;
___________________________________
So if Donte did not apply the distributive property correctly for 4*(1+3i)—and incorrect got 4 + 3i (as mentioned above); but did the rest of the problem correctly, he would have got:
_____________________________
4+ 3i - 8 + 5i = -4 + 8i (the incorrect answer as stated in our original problem.
__________________
This corresponds to: "Answer choice: [A]: He did not apply the distributive property correctly for 4(1 + 3i)."
