Answer:
A) l = w + 900
B) l * w = 4,000,000
B) l = 4,000,000 / w putting this into A)
A) 4,000,000 / w = w + 900
A) 4,000,000 = w^2 +900 w
A) w^2 +900 w - 4,000,000
Solving by quadratic formula
width = 1,600 length = 2,500
Double-Check
1,600 * 2,500 = 4,000,000
Length = width + 900
2,500 = 1,600 + 900
Answer is okay
Step-by-step explanation:
The second tank.
Since both filling up at the same rate, all you would have to do is multiply the gallons.
4/5 multiplying top and bottom by 8 is 32/40
7/8 multiplying top and bottom by 5 is 35/40
