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 .

7x . h . 2xm
You can put together 6x and x
but since h, and 2xm arent alike terms, you cant combine
It would be 3.22x10^8
have a good day
It would be 10 because 6.4 is greater than 5. Correct me if i’m wrong
X ≈ 9.33 units
Explanation:
As triangle DOG is similar to triangle CAT, the ratios of the sides are the same
AT/OG = CA/DO
x/4 = 7/3
x = 28/3
x ≈ 9.33
