(Simplify your answer.)

Area of the triangle is 20x(x - 1) sq. in

Step-by-step explanation:

Height = 10x in and Base = 4(x - 1) in

Area = 1/2 × base × height

⇒ Area = 1/2 × 4(x - 1) × 10x

            = 20x(x - 1) sq. in

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

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
