musickatia [10]

Answer:

25^4

Step-by-step explanation:

Here, we want to find the expression that shows the total number of pages in all of the news papers

Number of pages per book = 25

Number of schools is 25

Number of classrooms is 25

Number of students per classroom is 25

Now; the number of students in each school

is 25 * 25

Number of students in all of the school will be;

25 * 25 * 25

So the number of pages in all of the schools will be;

25 * 25 * 25 * 25 = 25^4

Hey, Its the same person. This is Algebra 2. Please Help!
suter [353]

Answer:

first option

Step-by-step explanation:

Given

f(x) = \frac{2x^2+5x-12}{x+4} ← factorise the numerator

     = \frac{(x + 4)(2x-3)}{x+4} ← cancel (x + 4) on numerator/ denominator

     = 2x - 3

Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is

x = - 4

Substitute x = - 4 into the simplified f(x) for y- coordinate

f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11

The discontinuity occurs at (- 4, - 11 )

To obtain the zero let f(x) = 0, that is

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}

There is a zero at ( \frac{3}{2}, 0 )

Thus

discontinuity at (- 4, - 11 ), zero at ( \frac{3}{2}, 0 )
