HELP THIS IS FOR A TEST!!!

The coffee cannot cover half a city block.

Step-by-step explanation:

300(300) = 90000

An average city block is 90000 square feet.

A gallon of water covers about 13.8 square feet.

Since we have 400 gallons of coffee, we will multiply 13.8 by 400.

13.8(400) = 5520

400 gallons of coffee covers 5520 square feet.

Half of 90000 is 45000, which means that the 400 gallons of coffee CANNOT cover half of a city block.

5520/90000 = 0.06

The 400 gallons of coffee can only cover around 6% of a city block.

`sqrt(8x^3 + 24x^2 + 18x)` = `sqrt(8x (x + 3/2))` = `sqrt(2x (4x + 6))` = ±(4x + 6) `sqrt(2x)`
