Because there is an absolute value in this equation around the x and and you are only adding something to that, we know that this will always be positive. This eliminates all the choices except for [1,infinity), the third option.
The Algebraic equations (x - 20)² and x² - 20 have an equal value My number is 6.
<h3>What is an Algebra equation?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result.
Let the number be x.
If I subtract 20 from my number that is x - 20 then square the result that is (x-20)².
And if I square my number that is x² then subtract 20 from the result that is x² - 20.
Both the result are the same then we have
(x - 20)² = x² - 20
x² - 20x + 100 = x² - 20
-20x + 100 = -20
x = 6
My number is 6

Answer:
the word similar means when to things are alike, it compares to congruent because congruent means thing are in harmony.
Things I would say are similar is a blanket and a sheet because they both provide coverage and warmth.
If I said things are similar it is because they are alike in meanings, or appearence.
I would use similar over congruent because congruent isn't a word you hear often. When you do hear it is mostly used to talk about angles and lines.

1. Subtract 15 to the other side (5x^2 = 36)
2.Square root both sides to remove the squared of 5x^2 (sqrt(5x^2) = sqrt(36) simplified to 5x = 6)
3. divide by 5 to get x = 6/5
Final result is 6/5
