Answer:-3
Step-by-step explanation:
4^2=16, 1^3=1, (-3)^2=9
so
16-1+3=18/(3-9)
so 18/-6= -3
Answer:
3 ln(x − 1) − 3/(x − 1) + C
Step-by-step explanation:
∫ 3x / (x − 1)² dx
3 ∫ x / (x − 1)² dx
If u = x − 1, then x = u + 1, and du = dx.
3 ∫ (u + 1) / u² du
3 ∫ (1/u + 1/u²) du
3 (ln u − 1/u + C)
3 ln u − 3/u + C
Substitute back:
3 ln(x − 1) − 3/(x − 1) + C
Answer:
Which gas creates the longest wavelength?
→Argon gas
Which gas creates the shortest wavelength?
→ Fluorine gas
Explaination:
1.0×10^-6 > 1.0×10^-7 > 1.0×10^-10 (a^-n =1/a^n)
The answer is B. (2 + x) + 3y.
The associative change happened when they just moved the parenthesis.
Hope this helps!
