Answer:

Step-by-step explanation:

-4(6x+3)= -12(x+10)

Let's do the first part:

-4(6x+3)

**distribute**

-4 x 6x = -24x; -4 x 3 = -12 ->>> -24x - 12

Let's do the second part:

-12(x+10)

**distribute**

-12 x x = -12x; -12 x 10 = -120 ->>> -12x -120

-24x -12 = -12x - 120

**Move variable to the left-hand side and change its sign**

-24x +12x -12 = -120

-12x - 12 = -120

-12x = 108

x = 108/-12

x=9

The continuity of $f'$ and its limiting behavior guarantees that $f'$ is Riemann integrable, so you can write

$\displaystyle\int_0^\infty f'(x)\,\mathrm dx=uv\bigg|_{x=0}^{x\to\infty}-\int_0^\infty v\,\mathrm du$

where $u=1\implies\mathrm du=0\,\mathrm dx$ and $\mathrm dv=f'(x)\,\mathrm dx\implies v=f(x)$ , so that

$\displaystyle\int_0^\infty f'(x)\,\mathrm dx=f(x)\bigg|_{x=0}^{x\to\infty}=\lim_{x\to\infty}f(x)-f(0)=-f(0)$

Answer:

They can seat 520 students.

Step-by-step explanation:

Given:

The night school auditorium is able to seat 8 elementary school groups of 65 students each.

Now, use the distributive property to determine the number of students they can seat.

Total number of elementary school groups = 8.

Number of students in each group = 65.
