Answer: The polygons are congruent when they are the mirror image of each other. They are equal in shape and size. They have equal number of sides. All the corresponding sides and corresponding angles are equal. It is different from similar polygons which have same shape but not necessary to have same size.
The solution set of the inequality 9x ≥ 117 is [9, ∞).
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, ∞).

100 and 28.
Explanation
Factors are number that you can multiply to give a certain number.
For example, 2 × 3 = 6. In this case 2 and 3 are factors of 6.
∴ To get the factors of 2800, we have to find numbers that you can multiply to give you 2800.
2800 / 2 = 1400
∴ 2 × 1400 = 2800. ⇒ 2 and 1400 are factors of 2800.
2800/100 = 28
∴ 100 × 28 = 2800 ⇒ 100 and 28 are also factors of 2800. 2800 have many factors but two of them are 100 and 28.
