Answer:
158.4 pounds
Step-by-step explanation:
first find the volume of the tank


to convert this to m^3 we know that 1m = 100cm


the cm^3 cancel out.


by simply converting the side-lengths to meters beforehand can give you this answer directly:

it is given that 1 meter cube of water weighs about 2200 pounds.

multiply both sides with 0.072 to find our answer: 


hence the weight of the water in the tank would be 158.4 pounds!

Answer:
Step-by-step explanation:
y = 2x^2 - 12x +19                Put brackets around the  1st 2 terms. Take 2
y = 2(x^2 - 6x ) + 19             Take 1/2 of the 6 square it and add inside the brackets
y = 2(x^2 - 6 + (6/2)^2) +19 Subtract 2 *9 from the 19. Express 1st 3 terms as ( )^2 
y = 2(x- 3)^2 + 19 - 18
y = 2(x - 3)^2 + 1
