A rectangle has a length of (3x - 1) and a width of (x + 1). Part A Determine the perimeter and area of the rectangle as polynomials.

Part B Determine the perimeter and area of the rectangle if x equals 5.

Part C Determine the perimeter and area of the rectangle if x equals 8.

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

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
