i think it is x= -7 and x=1
Step-by-step explanation:
i can't understand it clearly but i can sure its number 1 or letter A
I HOPE I'M RIGHT HEHE
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

If my math is right it should be B)
The answer is D
Pedro added $35, then took away $50 dollars, which graph D shows. Graph B also shows this, however it's in the wrong order, making it incorrect
Each centimeter on the map represents 20 miles in real life. Similarly, every twenty miles in real life would be represented as 1 centimeter on the map.
