What’s (2x-4)(6+5x) As a polynomial?

10x² - 8x - 24

Step-by-step explanation:

Given

(2x - 4)(6 + 5x)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(6 + 5x) - 4(6 + 5x) ← distribute both parenthesis

= 12x + 10x² - 24 - 20x ← collect like terms

= 10x² - 8x - 24

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
