Answer:
12.3-7.9x
Step-by-step explanation:
8.9+3.4=12.3
-1.4x+(-6.5x)=-7.9x
Sequence
8 - 7 = 1
15 - 8 = 7
23 - 15 = 8
38 - 23 = 15
For more sequences
38 + 23 = 61
Then
61 + 38 = 99
And so on the sequence continue
1.one hundred twenty thousand

Answer:
9√15·cis(19π/24)
Step-by-step explanation:
The magnitudes multiply and the angles add:
= ((3√3)(3√5))·cis(π/8 +2π/3)
= 9√15·cis(π(1/8 +2/3)) = 9√15·cis(π(3/24 +16/24))
= 9√15·cis(19π/24)
