How do you know when to factor a difference of squares versus a difference of cubes?

it just depends on if the number is a perfect square or perfect cube

Step-by-step explanation:

if the numbers something like 9 (3^2) then you'll factor using difference of squares where if its like 27 (3^3) then youll factor using difference of cubes

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
