Answer:
In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign "=".[2][3][4] The word equation and its cognates in other languages may have subtly different meanings; for example, in French an équation is defined as containing one or more variables, while in English, any equality is an equation.[5]
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
If you look at the Pythagorean theorem, a^2 + b^2 = c^2. Therefore if you square root all of sides, getting rid of the square, you will be left with the length of the sides.
3 < 3x - 3 ≤ 2x + 2
Adding -3 to each side gives
0 < 3x - 6 ≤ 2x - 1
The left inequality says
0 < 3x - 6 ⇒ 3x > 6 ⇒ x > 2
while the right inequality says
3x - 6 ≤ 2x - 1 ⇒ x ≤ 5
Then the solutions belong to the interval 2 < x ≤ 5 and contains only the integers x = 3, x = 4, and x = 5.
