Find the perimeter of a square if the length of one side is given. are the perimeter of the square and the length of its side directly proportional quantities? explain. 3 mi

Perimeter =12

Step-by-step explanation:

A square has 4 equal sides. So, the length and width have the same measurements in a square and the perimeter of the square and the length of its side directly proportional quantities.

The Perimeter of Square Formula is P=4s

                                                             P=4*3

                                                             P=12

So the perimeter is 12

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
