Step-by-step explanation:

#1. 4 x 2 + 1 =

8 + 1 =

9

add 40 + 9 = 49

#2. x + 2x + (x + 2x) = 6

6x = 6  

x = 1  

2x = 2

x + 2x = 3  

(2 x 100) + (3 x 10) + 1 or 231.

What is the quotient of the complex number 4-3i divided by its conjugate?
almond37 [142]

Answer: C. \frac{7}{25}-\frac{24}{25}i


Step-by-step explanation:

1. You have the following division:

\frac{4-3i}{4+3i} (As you can see, to find the conjugate of  4-3i you must change the sign between the terms).

2. To solve this division, you must multiply the numerator and the denominator by the conjugate of the denominator, as following:

=\frac{(4-3i)}{(4+3i)}\frac{(4-3i)}{(4-3i)}=\frac{16-12i-12i+9i^{2}}{16-9i^{2}}

3. Keeping on mind that i^{2}=-1, you have:

=\frac{16-12i-12i+9(-1)}{16-9(-1)}

4. Simplifying:

=\frac{7-24i}{25}=\frac{7}{25}-\frac{24}{25}i

5. The result is:

\frac{7}{25}-\frac{24}{25}i

Write the next three terms of the sequence.
Arada [10]

Answer:

25, 34, 43

Step-by-step explanation:

-11 + x = -2, -11 + 9 = -2                -2 + x = 7, -2 + 9 = 7,  7 + 9 = 16                             -2 - x = -11, -2 - 9 = -11                   7 - x = - 2,                                                               2 + x = 11,  11 - 2 = 9, 9 = x            7 - 7 = 0 - 2 = -2,   7 + 2 = 9,    7 - 9 = -2    

16 + 9 = 25,   25 + 9 = 34,   34 + 9 = 43              

J'espère que cela pourra aider : )
