Answer:
First of all it's a geometric sequence and it is multiplying 2 every time
Step-by-step explanation:
2*2=4
4*2=8
8*2=16
Factors always multiply each other.
The only option that multiplies something is (y^3 + 3)
So the answer is B.
X=16/3 or 5.33333 based on the fact that the angles are congruent
Percent change=100 times change/original
change=original-new
change=90-84.50=5.5
percent change=100 times 5.5/90
percent change=550/90
percent change=6.11111
percent change=6.1%
