hey guys, can someone explain the to me: If x > 0, then √x^3+x^2 −√4+4x = (x −2)√x+1 is the answer but I am not sure why.

do you have choises

Step-by-step explanation:

step-by-step explanation:

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
