What is the factored form of 8x^24-27y^6

Is it greater than or less than7*3_9*2

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function

Awater truck is filling a swimming pool. the equation that represents this relationship is y=19.75x where y is the number of gallons of water in the pool and x is the number of minutes the truck has been filling the pool.
