- x³ - 15x² - 61x - 36

Step-by-step explanation:

Given

(x² - 5x - 4)(x² + 4x + 9)

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

x²(x² + 4x + 9) - 5x(x² + 4x + 9) - 4(x² + 4x + 9) ← distribute parenthesis

= + 4x³ + 9x² - 5x³ - 20x² - 45x - 4x² - 16x - 36 ← collect like terms

= - x³ - 15x² - 61x - 36

Check as the pic above showed

36 is the final answer! : )

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
