The notation A = {0,1, 2} is an illustration of sets

The set A do not have isolated points

<h3>What is an isolated point?</h3>

An isolated point is an element of a set that belongs to a set A and any neighboring sets N, such that the set N do not contain other elements of set A

<h3>The isolated point for set A?</h3>

The set A is given as:

A = {0,1, 2}

The elements of the set A do not exists in other sets

So, we can say that set A do not have isolated points

Question part points submissions used consider the following. g(x)={((x**2-a**2)/(x-a) text(if ) x != a,4 text(if ) x =

EastWind [94]

For $x\neq a$ , we have

$\dfrac{x^2-a^2}{x-a}=\dfrac{(x-a)(x+a)}{x-a}=x+a$

So for $g(x)$ to be continuous at $x=a$ , we require that the limit as $x\to a$ is equal to 4.

$\displaystyle\lim_{x\to a}g(x)=\lim_{x\to a}(x+a)=2a=4\implies a=2$

Leah knit a scarf that is 130 centimeters long, Theo knit a scarf that is 4/3 as long

Delvig [45]

Answer: Theo's scarf is 173 + 1/3 centimeters long.

Step-by-step explanation:

The scarf of Leah is 130 centimeters long.

The one of Theo is 4/3 as long as the one of Leah, then we have that the length of the scarf of Theo is:

Lenght = (4/3)*130 cm =(4*130)/3 cm =520/3 cm

Now, we know that if all the digits of a number add up to a multiple of 3, that number is divisible by 3.

520/3 = (519 + 1)/3 = 519/3 + 1/3 = 173 + 1/3

Theo's scarf is 173 + 1/3 centimeters long.

Which statement shows how the product of (x + 7)2 demonstrates the closure property of multiplication?

Illusion [34]

<h3>(x + 7)² = x² + 14x + 49</h3>

The true statement that show the closure property of multiplication :

<h3>a. x² + 14x + 49 is a polynomial</h3>

$\texttt{ }$

<h3>Further explanation</h3>

<em>If equation ax³ + bx² + cx + d = 0 has roots x₁ , x₂ , and x₃ then</em>

$x_1 + x_2 + x_3 = - \frac{b}{a}$

$x_1 x_2 + x_1 x_3 + x_2 x_3 = \frac{c}{a}$

$x_1 x_2 x_3 = - \frac{d}{a}$

Let us now tackle the problem!

$\texttt{ }$

This problem is about Polynomial.

$(x + 7)^2 = (x + 7)(x + 7)$

$(x + 7)^2 = x^2 + 7x + 7x + 7(7)$

$(x + 7)^2 = x^2 + 14x + 49$

$x^2 + 14x + 49$ is a polynomial.

$x + 7$ is polynomial.

It demonstrates the closure property of multiplication.

<h3>a. x² + 14x + 49 is a polynomial</h3>
