I think the correct answer from the choices listed above is option C. The values of x and y that would make the expression to represent a real number would be that <span> x = 4, y = –5. Substituting and simplifying,
</span><span>(4 + 5i)(4 - 5i)
</span>16 - 20i + 20i - 25i²
16 - 25(-1)
16 +25
41
Answer:What are some accessory organs to digestion and what do they do?
Explanation:The salivary glands, liver and gall bladder, and the pancreas aid the processes of ingestion, digestion, and absorption. These accessory organs of digestion play key roles in the digestive process. Each of these organs either secretes or stores substances that pass through ducts into the alimentary canal.
1) The law of orbits. This is when all planets move in elliptical orbits, with the sun at once focus.
2) The law of areas. A line that connects a planet to the sun sweeps out equal areas in equal times.
3) The law of periods. The square of the period of any planet is proportional to the cube of semimajor axis of its orbit.
These laws were derived for orbits around the sun, but they apply to satellite orbits also. I hope this helps! ~Mia
The answer that makes the most sense is number one or two. Number 3 and number four both makes no sense in that context. Most of the time an animal will not die or mutate due to a parasite in its body.
