The correct answer is c. D might be seen as the right answer but c is correct. C is correct because x cancels out making it a no solution
3x^2 - 2x^2y + 2xy^2 + 4y^2 + xy^2 - y^2 + 2x^2y
= 3x^2 + 3y^2 + 3xy^2
answer
3x^2
3y^2
3xy^2

Answer:
45,489.6 pounds!
Step-by-step explanation:
To solve this problem, first we need to find the volume of the pool.
We know that the dimensions of the pool are:
Width = 9ft
Length = 18ft
Height = 54in = 4.5 ft
So the volume of the pool is:
Volume = Width x Length x Height = 9ftx18ftx4.5ft = 729ft^3
We know that one cubic foot of water weights about 62.4 pounds. To fill the pool, we will need 729ft^3 of water.
So the weight of the water is:
Weight = 729ft^3 x 62.4 pounds/ft = 45,489.6 pounds!
