Answer:
Real
Step-by-step explanation:
i^6-122-7i^2
(i^2)^3-122-7i^2
(-1)^3-122-7×(-1)
-1-122+7
-123+7
-116
So the final answer is -116
The answer is A.
When simplifying radicals, you can factor out anything that is a root. In this case we have a 4th root. We can break 144 to 16*9. By doing this, we can pull out 16 which has the 4th root 2 (2*2*2*2=16). Next, a^12 has the 4th root a^3. We can't do anything with the b^3 so it stays inside the root with the 9.
I feel like some information is missing here.
4 out of 5 games is 80%:

So if we know, as a rule that "<span>Joel scores in 80% of his games.", the probability that he will score in 80% of his games is 1 - that is, we know it for sure</span>
It’s the red one because that what it is and this answer is this long because I needed 20 characters at least.
Answer:
weight of the kitten last year = 9 ounces
Step-by-step explanation:
Let
x = weight of the kitten last year
Weight of the kitten this year = 2 1/3 * x = 21
7/3*x = 21
7/3x = 21
x = 21 ÷ 7/3
x = 21 × 3/7
= 63/7
x = 9 ounces
weight of the kitten last year = 9 ounces
