Answer:

$27

Step-by-step explanation:

Set up a proportion where x is the amount of money he saved:

\frac{12}{9} = \frac{36}{x}

Cross multiply and solve for x:

12x = 324

x = 27

So, he saved $27

What is the square root of -1​
Romashka [77]

Answer:

i

Step-by-step explanation:

Now, before you think I'm just stealing points, let me explain. The square root of a number is the number that, if you multiply it by itself, it equals that number. The square root of 4 is 2, because 2 * 2 = 4.

Also, a negative number times another negative number, is a positive number. -2 * -2 = 4

With both of those true, then what number could be multiplied by itself to equal a negative number? i.

i is a weird number that I don't really know how to explain all that well. I am sorry, but that is all that I can give you. i is very complex and has various different equivalents, and different meanings, but i is equal to \sqrt{-1}.

Hope that this helps!
