Luckily the true statement is there, otherwise you'd have to post more. When x = -5,

x^2 + 10 = (-5)^2 + 10 = 25 + 10 = 35

x + x + x = 3x = 3* - 5 = - 15

x^2 + 10 > x + x + x That's the first choice

5 * 8.4 = 42
10^-15 * 10^8 = 10^-7

length = 42 * 10^-7

in scientific notation this is 4.2 * 10^-6

Factorise using identity 4y^2 - 12yz+9z^2

Andrew [12]

Step-by-step explanation:

Identity used  :

$\bold{ ({y}^{2} + {z}^{2}) = {y}^{2} + 2yz + {z}^{2} }$

$\implies \: {(2y)}^{2} - 2.2y.3z + {(3z)}^{2}$

so we got :

y = 2

z = 3

${ \pink{ \bold{ \boxed{answer = (2y + 3z) {}^{2} }}}}$

Describe the set of all complex numbers that are at a distance of 2 units from the origin.

Andreyy89

Answer:

The description of the set is $A = \{s\in \mathbb{C}|\|s\| = 2\}$ .

Step-by-step explanation:

From Complex Analysis, we remember that complex numbers are numbers whose form is:

$s = a+i\, b$ , $a,b \in \mathbb{R}$ (1)

Where $i = \sqrt{-1}$ .

In addition, the distance from the origin is defined by the following Pythagorean identity:

$\|s\| = \sqrt{a^{2}+b^{2}}$ (2)

The following condition must be satisfied:

$\|s\| = 2$

Then, the set of all complex numbers that are at a distance of 2 units from the origin is described below:

$A = \{s\in \mathbb{C}|\|s\| = 2\}$ (3)
