Step-by-step explanation:

Let's solve your equation step-by-step.

-9v-9=-27

Step 1: Add 9 to both sides.

-9v-9+9=-27+9

-9v=-18

Step 2: Divide both sides by -9.

-9x = -18

-9 -9

v=2

Answer:

v = -2

Step-by-step explanation:

-9v – 9 = -27

add 9 to each side

-9v – 9+9 = -27+9

-9v = -18

divide by -9

-9v/-9 = -18/-9

v = 2

$\begin{array}{l} \displaystyle \int \dfrac{4 - 3x^2}{(3x^2 + 4)^2} dx \\ \\ = \displaystyle \int \dfrac{4 - 3x^2}{x^2\left(3x + \dfrac{4}{x}\right)^2} dx \\ \\ = \displaystyle \int \dfrac{\dfrac{4}{x^2} - 3}{\left(3x + \dfrac{4}{x}\right)^2} dx \\ \\ \text{Let }u = 3x + \dfrac{4}{x} \implies du = \left(3 - \dfrac{4}{x^2}\right)\ dx \\ \\ \text{So the integral becomes} \\ \\ = \displaystyle -\int \dfrac{du}{u^2} \\ \\ = -\dfrac{u^{-2 + 1}}{-2 + 1} + C \\ \\ = \dfrac{1}{u} + C \\ \\ = \dfrac{1}{3x + \dfrac{4}{x}} + C \\ \\ = \boxed{\dfrac{x}{3x^2 + 4} + C}\end{array}$
