Answer:
8
Step-by-step explanation:
to find the answer, subtract the second amount (2) from the first amount (-6), -6 - 2 = -8, the temperat decreased by 8
Let x be the first odd number.
Second odd number will be x+2
Proof:
If 3 (was) the first odd number, 3+2 would be the next which is 5.
So,
(x) (x+2) = 99
xsquare + 2x = 99
xsquare +2x - 99 = 0
xsquare +11x - 9x -99 = 0
x(x +11) -9(x + 11) = 0
(x+11) (x-9) = 0
So the two odd numbers were 9 and 11
The best way is to do problems over and over again and making mistakes with them.There is no point in doing them if you get correct answers.
When you make mistakes you ask someone what’s wrong and try not to make that mistake again.
That’s how I became a master at maths and physics.
As for help with calculus the important thing is to understand how graphing works.
Once you got that do more questions.
So basically to summarise make mistakes don’t repeat and find out how it works
Hope this helps:)

Answer: 1848 cubic meters</h3>
=================================================================
Explanation:
Imagine rotating the figure so that the triangular face is flat on the ground. This makes the triangular faces to be the floor and ceiling of this room.
The floor is a triangle with base 24 meters and height 7 meters. The floor area is base*height/2 = 24*7/2 = 84 square meters.
Multiply this floor area with the height of the room (22 m) to get the volume of the room.
volume = (floor area)*(height) = 84*22 = 1848 cubic meters
