Answer:
x+9
Step-by-step explanation:
4x³+12x²-72x
=4x(x²+3x-18)
=4x[x²+6x-3x-18]
=4x[x(x+6)-3(x+6)]
=4x(x+6)(x-3)
The first one is 100 because it is closer to 100 than to 200. The second one is 700 because 690 is 10 away from 700. And the third one is 100 because it is only 15 away from 100.
Step-by-step explanation:
Cost to make the film : $6500
Cost to set up production: $1500
Additional cost to make each video : $4
Additional cost to make n videos : $4n
total cost to make n videos = $6500 + $1500 + $4n = (8000 + 4n) dollars
overall cost to make each video
= total cost to make n videos ÷ n videos
= (8000 + 4n) / n
by definition, in order to "break even", the selling price for each video must be equal to the cost to make each video. i.e
Price, P(n) = (8000 + 4n) / n
Hence,
P(500) = [8000 + 4 (500)] / 500 = (8000 + 2000) / 500 = $20
This means that in order to break even selling 500 DVD's he has to sell each one for $20
9x + 2 + 8x + 1 = 17x + 3
The answer is 180 - 17x + 3 I'm pretty sure
Answer:
The thermal energy that drives the rock cycle comes from two main sources: Earth's intcriw and the sun. Earth's cutan is also a source of thermal energy that drives the rock cycle. This thermal energy is the result of radioactiv Within Earth's crust, mantle, and core.
Hope this helps :)
