Answer:
I'll give it straight: the following are rational numbers.
- Whole numbers
- Terminating decimals
- Repeating decimals
- Improper fractions (and all other fractions)
- (Integers, too)
- If square root is whole number, square root of a square is perfect, and therefore, rational
- Since a rational number is any number that can be written as a fraction, if a mixed number, such as 1 1/2, can be written as a fraction, then it is rational (1 1/2 can be written as 3/2, therefore it is rational)
Step-by-step explanation:
Answer:
a² - 5a - 36
Step-by-step explanation:
(a - 9)(a + 4)
each term in the second factor is multiplied by each term in the first factor, that is
a(a + 4) - 9(a + 4) ← distribute parenthesis
= a² + 4a - 9a - 36 ← collect like terms
= a² - 5a - 36
