you spend 28 and want 20 profit
28 +20 = 48 total
48/4 = 12
answer is D, you need to sell 12 containers
Answer:
OXY=18
Step-by-step explanation:
The ratio of AABC to AAXY is 4:3 so the lengths will be in that ratio too. The ratio of BC:XY is 4:3. BC is 24 so 24:XY is 4:3. You need to divide 24 by 6 to get 4 so multiply 3 by 6 to get the answer 18.
Answer:
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)
Step-by-step explanation:
(X^2 + x - 6) (2x^2 + 4x) =
Let's open the brackets carefully
x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x
= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)

Determine the surface area
The figure is made up of two cuboids and the surface area of a cuboid is:
Because the bottom part of the upper piece is not visible, the area is calculated as:
This gives:
For the bottom piece:
We calculate its area as . However, the area of the invisible part will be subtracted.
So, we have:
The total surface area is:
