Integration will be ln | ( x /9 ) + ( 
) | + c .
Given ∫ 1 dx / ( 
- 81 )
Put ,
x = 9 secθ
dx = 9 secθ tanθ dθ
and
= 9 tanθ
Substituting values in ∫ 1 dx / ( - 81 ) ,
∫ (9 secθ tanθ ) dθ / ( 9 tanθ )
∫ secθ dθ = ln | secθ + tanθ | + c
= ln | ( x /9 ) + ( / 9 ) | + c
= ln | ( x /9 ) + ( ) | + c
Hence , the integration will be ln | ( x /9 ) + ( ) | + c .

Answer:
for 6: -2x+30
I dont know for # 8
Step-by-step explanation:
to distribute, you have to multiply -3 by x and -10.
-3(x) - -3(10) + x =
-3x + 30 + x:
then you have to add common terms
-3x + x = -2x
then replace that in your equation to get:
-2x +30
