Question

use the list below to complete the sentences. constants variables simplify 1. you can combine like terms to an expression. 2. all are like terms and can be combined. 3. terms with the same are considered like terms. for each of the following, tell whether the terms shown are like terms or unlike terms. 4. -5x, -5, 0.5x like terms unlike terms

Explanation:

1. Combining like terms reduces an expression to its shortest form.
2. Constants are terms without variables, so they are all like terms.
3. Like terms share identical variable parts.
4. $-5x$ and $0.5x$ have the same variable $x$, while $-5$ is a constant with no variable.

Answer:

1. simplify
2. constants
3. variables
4. $-5x$ and $0.5x$ are like terms; $-5$ is unlike the other two terms
