Find the product of (x + 5)2.

x2 − 10x + 25
x2 − 25
x2 + 25
x2 + 10x + 25

if the question is (x + 5)^2, the product is x^2 + 10x + 25.

because they could drop even lower..

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
