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 
.
Hope that this helps!
2+12a. When adding, you're only collecting "like terms".
Hey there :)
f (x) = 5x² - 2x
g (x) = 3x² + x - 4
( f + g )( x ) is f ( x ) + g ( x )
5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4
Your option will be the third option
Use “Photo math” in the app store. It’ll help you with all those type of problems:)
You can set up 2 equations for the two companies that sell pizza. Pizza A's will be:
And B's will be:
To find the number of toppings we will need to make the companies prices equal can be found by setting the equations equal to each other and solving for x, because x is the price per topping. So:
So, the
number of toppings you will need is 5 toppings to make their prices equal. *If any step is unclear, then hmu!
