V = lwh
V = x(2x + 3)(2x + 5)
V = x(2x(2x + 5) + 3(2x + 5))
V = x(2x(2x) + 2x(5) + 3(2x) + 3(5))
V = x(4x² + 10x + 6x + 15)
V = x(4x² + 16x + 15)
V = x(4x²) + x(16x) + x(15)
V = 4x³ + 16x² + 15c

The answer is D.

What is this solution of the equation 4w = 2/3
amid [387]
First, you need to isolate w. So you get w = 2/3 divided by 4.
I made the 2/3 a decimal, as it is easier to work with: 0.6666 divided by 4 is 0.167. 
0.167 is 1/6.
w = 1/6, or 0.167.

Answer:

8 bags

Step-by-step explanation:

You divided them by 20 which gives you 4. So you take the 3 and multiply by 4 which is 12 bags. And then you do the same for your bags which makes you do 2 times 4 which gives you 8. You take 20 - 12 and that leaves you with 8.
