The answer would be B. About 92 cubic feet. Have a good rest of your day.
First expand it
Next subtract 14 - 2x + 4x so it can be 14 + 2x
Next subtract 14 from both sides
Next subtract 20 - 14 so it can be 6
Then divide both sides by 2
And lastly reduce the fraction 6/2 and once u reduce it u have your answer which is x = 3.
Substitute p and q with the given numbers (6 and 5) then use pemdas
18+42/6-5= 20
I think 4.2 x 10^6 is the answer you're looking for.
