The solution set of the inequality 9x ≥ 117 is [9, ∞).
What are inequalities and their types?
Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, An inequality 9x ≥117.
Dividing both sides by 9 we have,
(9/9)x ≥ 117/9.
x ≥ 13.
Therefore, The solution set of the inequality is [9, ∞).

Step-by-step explanation:
The expression (3x - 40)° (2x + 23)° represents the product of two angles, (3x - 40)° and (2x + 23)
(3x - 40)° (2x + 23)° = (3x - 40)(2x + 23)°
3x - 40)(2x + 23)° = 3x(2x + 23) - 40(2x + 23)°
3x(2x + 23) - 40(2x + 23)° = 6x² + 69x - 80x - 920
6x² + 69x - 80x - 920 = 6x² - 11x - 920
simplified expression of (3x - 40)° (2x + 23)° is 6x² - 11x - 920.

Boiling water measures 100 degrees in Celsius, and 212 degrees in Fahrenheit. Freezing water measure 0 degrees in Celsius, and 32 degrees in Fahrenheit.
So, if you want to convert Celsius into Fahrenheit, you will need to:
Multiply by 180/100
Add 32
Let's convert 30 degrees Celsius into Fahrenheit.
30
54 + 32 = 86
