I don’t really understand this question so I will try to figure it out later
Answer:
-5 + 12 i
Step-by-step explanation:
(2 + 3i)^2 = 4 + 6i + 6i + 9i^2
= 4 + 12 i + 9(-1)
= - 5 + 12 i
Answer:
0.66 = 66%
Step-by-step explanation:
If we know that a odd-numbered disk is selected, we know that the number is 1, 3 or 5.
So, if it is a red disk, is can be number 1 or 3, so we have two possibilities.
If it is a yellow disk, it needs to be number 5, so we have just one possibility.
We have a total of 3 possibilities, and 2 of them are with red disks, so the probability is 2/3 = 0.66 = 66%

Answer:
Step-by-step explanation:
<em>We have to solve the inequality for x.</em>
<em>Solution is given below.</em>
7x +16 < -5(4 - 5x)....given
7x + 16 < -20 + 25x....distributive property
16 < -20 + 18x ... subtraction property
16 + 20 < 18x.....addition property
36 < 18x
36/18 < x.....division property
2 < x
