5353 minutes = 89.22 hours
Maybe the figures should be 53 and 20??
Let's let Billy = A
The formula to use for work problems is
Time = (A*B) / (A+B)
53 = ( (A +20)* A) / (A +20 + A) )
53 = ( A^2 + 20A ) / (2A + 20)
A^2 + 20A -106A -1060
A^2 -86A -1060
A = 96.935

Answer:
4x^2 − 4x −1 + 11 / x+1
Step-by-step explanation:
The answer is
4x^2 − 4x −1 + 11 / x+1
The volume is 336 cubic feet
6x8x3 = 144
8x4x6= 192
144+192=336
