When we take the square root of each side, the equation would become:
abs (x+2) = 2
⇒ x+2 = <span>±2.
The final answer is </span><span>x + 2 = ±2.
</span>
Hope this helps~

Step-by-step explanation:
To re-phrase this: 50 is a certain percent of 90.
this can be written mathematically as 50=x%*90
let's divide both sides by 10:
5=x%*9
and divide both sides by 9:

which in decimals is approximately 0.56 (but not exactly).
so 0.56=x%
and the x then 56
so 50 is
approximately 56% of 90:
exactly 56%of 90 is 50.4
Answer:
Since 6 lemons are used to make 4 cups of lemonade, then are used
of lemon per cup of lemonade, or are make
cups of lemonade per lemon.
Let <em>x</em> = 8.132132132...
Then 1000<em>x</em> = 8132.132132132...
Subtract <em>x</em> from 1000<em>x</em> to eliminate the fractional part:
1000<em>x</em> - <em>x</em> = 8132.132132132... - 8.132132132...
999<em>x</em> = 8132 - 8 = 8124
<em>x</em> = 8124/999 = 2708/333
