Answer:
D) 1
Step-by-step explanation:
When you start raising i to certain powers, you begin to notice a pattern.
This cycle repeats forever. Since 84 is a multiple of 4, i^84 must be 1. Hope this helps!
Hey there!
Let's set up our expression:
(7a-6b+7)-(8a-2)
In order to simplify, we can use that subtraction sign and distribute it, using the distributive property. We have:
7a-6b+7-8a+2
Notice how it's plus two, because a negative times a negative two is a positive two. Now, it's a matter of finding the like terms and adding or subtracting them. These like terms can either have no variable, or have different coefficients but the same variable. That means our like terms are the 7a and -8a, and the 7 and 2. There's no like term for the 6b. That means we have:
(7a-8a) - 6b + (7+2) =
-a - 6b + 9
Hope this helps!
so... you tells us, which filling rate is the bigger and thus faster one?
