Answer:
New position = -525 ft or 525 ft below the sea level
Step-by-step explanation:
Lets h be the height of the sea.
Given:
A submarine was situated 800 feet below sea level.
It is ascends 275 feet.
We know that h = 0 on the surface of the sea.
When we go below the surface vertically inside the sea the height will become negative.
So the submarine was situated h = -800 feet below the sea level, and it is ascends 275 feet from -800 feet.
So the new height of the submarine is.


Therefore the new position of the submarine is 525 below the sea level.
Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
Answer:
Only 1 plane containing line L can be drawn parallel to plane P.
Step-by-step explanation:
Line L is an axis of an infinite number of planes that can contain it. Line L is a straight line suspended over or below plane P.
All the planes that can contain line L would be almost infinte. Spinning around this axis of line L, the planes that can contain line L will be always be at an angle to plane P except for one position. In this position the plane containing Line L would face straight up to the plane P, hence, this is the only parallel case.

18 you multiply the 6 to the 3 so if it took her 3 minutes for 2 it will take her 18 minutes for 12
