First step: Factor the expression.
(x + 8) / (x - 6)(x + 4)
Set each factor of the denominator equal to zero.
x - 6 = 0 x + 4 = 0
add 6 to both sides subtract 4 from both sides
x = 6 x = -4
The function would be undefined if x = 6 or x = -4

Answer: n = -2

Step-by-step explanation:

3n +2(n + 2) = 9n + 12

(simplify 2(n + 2)) =

3n + 2n + 4 = 9n + 12

(subtract 9n from both sides)

3n + 2n - 9n + 4 = 12

-4n + 4 = 12

(subtract 4 from both sides)

-4n = 8

(divide -4 from both sides)

n = -2

How do the angle measures of polygon ABCD compare with the angle measures in the reflected image? How do the side lengths compar

Tresset [83]

The measures of the angles ABCD are the same as the measures of the angles that is corresponding based on the reflected images.

<h3>How to show that the angles are equal</h3>

Based on the fact that this is a reflection, the angles would be equal measures.

What this means is that there is a preservation of the of the reflected image. This is the same logic for the length of the sides.

The reflection is known to be a rigid type of transformation that is known to have its angles and sides preserved.

Given the formula A = P(1 + )". compute A (rounded to two decimal places) if P = 10,000,7

Flura [38]

Answer:

A = 16010.32

Step-by-step explanation:

Given that,

$A=P(1+\dfrac{r}{k})^n$

Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.

$A=10,000(1+\dfrac{0.08}{2})^{12}\\\\=10,000\times (1.04)^{12}\\\\=16,010.32$

So, the value of A is 16010.32. Hence, the correct option is (B).

1. A Babylonian tablet found in 1936 shows that the Babylonians sometimes used a more accurate value of π than 3. They determine

madreJ [45]

Answer:

Step-by-step explanation:

Area of a circle is given as πr² and its circumference is expressed as 2πr.

If the babylonians determined the area of a circle by taking it as equal to the square of the circle’s circumference then;

Area of circle = (circumference of a circle)²

πr² = (2πr)²

πr² = 4π²r²

Dividing both sides of the equation by πr² we have;

$\frac{\pi r^{2} }{\pi r^{2} } =\frac{4\pi^{2} r^{2} }{\pi r^{2} }\\1 = 4\pi \\\pi =\frac{1}{4}$

The value of π this yields is 1/4

Which answer choice shows 4 + 0.3 + 0.09 written in standard form?

puteri [66]

Solution:

<u>A few changes were made:</u>

4 as 4.00.
0.3 as 0.30

<u>New equation:</u>

4 + 0.3 + 0.09 = 4.00 + 0.30 + 0.09

<u>Solving the equation:</u>

4.00 + 0.30 + 0.09
=> 4.39 (Refer to image for work)

Correct option is B.
