Answer:
5+23
Step-by-step explanation:
increased by is another word for add
If your answer was d) 3.6 , then you are correct!

Negative temperatures are basically the same as normal ones, although they go below zero, so they are still the same distance apart from zero, just on the left side of the number line.
To find the answer find the difference between 30.5°C and 0 (which is 30.5).
Next, find the difference between -122.2°C and zero (122.2)
Finally, add 122.2 + 30.5 to find the total distances from the zero combined for the full distances apart from each other.
(We add them because -122.2 to the left of zero, and 30.5 is on the right)
You should get 152.7 as your answer.

I'm guessing since it is asking for the deepest point (-5315) from sea level (0), the answer is -5,315 feet
*Remember 5,315 is negative because numbers below sea level are all negative*
So the answer should be -5,315 feet deep. (I'm not sure how to show your work for that I'm guessing it is 0 - 5,315 at the slightest).
*Hope this all helped :)*

Answer:
(3x^2 - 1)(3x^2 + 1)(9x^4 + 1).
Step-by-step explanation:
Using the identity for the difference of 2 squares;
a^2 - b^2 = (a - b)(a + b)
we put a^2 = 81x^8 and b^2 = 1 giving
a = 9x^4 and b = 1, so:
81x^8 − 1 = (9x^4 - 1)(9x^4 + 1)
Applying the difference of 2 squares to 9x^4 - 1:
= (3x^2 - 1)(3x^2 + 1)(9x^4 + 1).
