Answer:
Water remaining in the pool after 141 days = 14,505 gallons
Step-by-step explanation:
Total number of gallons of water in the pool = 15,069
Rate of leakage of water = 4 gallons per day
Using unitary method
1 day leakage of water from the pool = 4 gallons
∴ In 141 days leakage of water from the pool will be = 
gallons
After leaking 564 gallons of water, total gallons of water that will remain in the pool will be = 
gallons
Answer:
x = 9; y = 12; u = 24; v = 32
Step-by-step explanation:
The corresponding sides of similar triangles are in the same ratio to each other.
3/5 = (3 + x)/20 Multiply each side by 20
20×3/5 = 3 + x
12 = 3 + x Subtract 3 from each side
x = 9
=====
4/5 = (4 + y)/20 Multiply each side by 20
20×4/5 = 4 + y
16 = 4 + y Subtract 4 from each side
y = 12
=====
3/5 = (3 + x + u)/60 Multiply each side by 60
60×3/5 = 3 + x + u
36 = 3 + x + u Insert the value of x
36 = 3 + 9 + u
36 = 12 + u Subtract 12 from each side
u = 24
=====
4/5 = (4 + y + v)/60 Multiply each side by 60
60×4/5 = 4 + y + v
48 = 4 + y + v Insert the value of y
48 = 4 + 12 + v
48 = 16 + v Subtract 16 from each side
v = 32
x = 9; y = 12; u = 24; v = 32
10^4 in expanded form would be 10,000
7y + 2x - 10y + 3x² - 10x
3x² - 10x + 2x + 7y - 10y
3x² - 8x - 3y
