Answer:
22 1/2
Step-by-step explanation:

All in all, there are 24 dvds and choosing 3 of them will give us,
24C3 = 2024 ways
2024 ways. If we are to select the dvd as given in the order above, we can use the basic principle of counting such that,
5 x 8 x 11 = 440
Dividing the second number by the first and multiplying by 100% will give us an answer of 21.739%.
Answer:
Step-by-step explanation: I believe you would just take 147 + 224 + 175 + 273 = 819pi cm2
So your answer would be 819pi cm2
Answer:
-5+√3i is the given root so -5-√3i must be the other root
Step-by-step explanation:
We know that complex roots must come in pairs. The pairs are complex conjugates. (a+bi) and (a-bi)
You are missing a sign between -5 and the square root
So if - 5+ sqrt(3) i is a root, then -5 - sqrt(3) i must be a root
if -5 - sqrt(3)i is a root, then -5 + sqrt(3)i must be a root.
I will assume you missed a + sign
-5+√3i is the given root so -5-√3i must be the other root
