s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
1st multiply 2 x 8 x 144 = 2304 in^3divide 2304 by 144 = 16 board feet
To solve A, complete the square for both variables.
The center is (6,4)
320 qts/10 hrs = 32 qts/1 hr
They can make 384 quarts in 12 hours.
They can make 768 quarts per day (24 hours) if they open 24 hours.
I think its 384 because if you multiply the two numbers underneath then you get 384 which is how they got all the other numbers
