Answer:
B.
Step-by-step explanation:
2x²(3x³ - 9x +27)
= 6x^5 - 18x³ + 54
If +15 is also a a part of the power of 216 there will be no solution:
216^(-1.5t)=1-15
216^(-1.5t)=-14
-1.5t= 216 base log -14 as log with negative value(-14 in this problem) has no solution so,
I guess it is 216^(-1.5t+15)=1 right?
216^-1.5t+15=1
-1.5t+15=216 base log 1
-1.5t+15=0(Any log with value 1 of anybase has no value which is peopwely 0)
-1.5t=-15
t=15/1.5
t=10

Answer:
C. 82
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. So ...
(x + 10°) + 88° = 180°
x = 180° -98°
x = 82°
