For this case we have the following expression:

(-3 + 6i) (- 3 + 5i)

To solve the problem, we apply the distributive property.

We have then:

(9 - 15i) + (-18i + 30i ^ 2)

Rewriting we have:

30i ^ 2 -33i + 9\\30 (-1) -33i + 9\\-30 -33i + 9\\-33i - 21

Therefore, the answer for this case is:

-21-33i

Answer:

-21-33i

Note: review the options again. The answer does not seem to be among the options.

The sum of 5 consecutive even numbers is 310. What is the third number in this sequence?
bija089 [108]
A simple way to solve for consecutive numbers is to divide the sum number by the number of numbers needed. So 310 ÷ 5, which equals 62. That is the middle consecutive number.

To find the other 4 numbers, since they are all even, sinply add 2 to the middle number to find one, add 2 to that to find another, subtract 2 from the middle number to fine the third, and subtract 2 from that to find the final one.

62 + 2 = 64
64 + 2 = 66
62 - 2 = 60
60 - 2 = 58

so your numbers are 58, 60, 62, 52, and 66. Together they add up to 310.

(I may have done this a non-standard way, bit it was the way that made the most sense in my head.)
