8u/u^2-18u+81 subtract 72/u^2-18u+81

Karo-lina-s [1.5K]

Your question is:
$\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}$
Then, the above formula equate:

$\frac{8u-72}{u^2-18u+81}$
Factor out 8 from the numerator we get:
$\frac{u-9}{u^2-18u+81}$
Factorization of the denominator:
$\frac{u-9}{(u-9)^2}$
Simplifying the numerator and the denominator by (u-9) we get:
$\frac{1}{(u-9)}$

10 - |3n - 2| = -9<br><br>please help :D

lapo4ka [179]

Answer:

n =7 or n = -17/3

Step-by-step explanation:

10 - |3n - 2| = -9 (subtract 10 from both sides)

- |3n - 2| = -9 - 10

- |3n - 2| = -19 (multiply both sides by -1)

|3n - 2| = 19

(3n - 2) = 19 or (3n - 2) = -19

For (3n - 2) = 19,

3n - 2 = 19

3n = 21

n =7 (answer)

For (3n - 2) = -19,

3n - 2 = -19

3n = -17

n = -17/3 (answer)
