State how many imaginary and real zeros the function has. f(x) = x3 - 20x2 + 123x - 216

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?

Which two undefined geometric terms always describe figures with no beginning or end?
