1.

$2\cdot x^2+2\cdot x^1+1\cdot x^0=25\\2x^2+2x+1=25\\2x^2+2x-24=0\\x^2+x-12=0\\x^2+4x-3x-12=0\\x(x+4)-3(x+4)=0\\(x-3)(x+4)=0\\x=3 \vee x=-4$

The base can't be negative, therefore $x=3$ .

$3\cdot x^0+3\cdot x^1+4\cdot x^0-4\cdot x^1+0\cdot x^0=0\\3+3x+4-4x=0\\x=7$

How do I solve this equation? 3|13-2t|=15

Nikolay [14]

$3 |13 - 2t | =15$ ⇒ $|13-2t| = 15\div3$ ⇒ $\boxed {|13-2t| = 5}$

$\hbox {We have two equations : 1. } |13-2t|=5$
$2.|13-2t|=-5$

$\hbox{The first: }$ ⇒ $13-2t=5$ ⇒ $2t=13-5$ ⇒ $2t=8$ ⇒ $\boxed {t=4}$

$\hbox { The second: } 13-2t=-5$ ⇒ $2t=13-(-5)=18$ ⇒ $\boxed {t=9}$

Answer: 18 animals

Step-by-step explanation:

3 out of 20 pet owners get their pet from a breeder.

To find how many animals have been bought from a breeder, you need to find 3/20 of the 122 animals.

3/20 = 0.15

122 * 0.15 = 18.3

18.3 rounds down to 18

There are 18 animals who have been bought from a breeder.
