Question

What are the like terms, coefficients, and constants in the equation 2+3a+9a

Answer 1

Like Terms:
`3a` and
`4a`.

Coefficients:
`3` and
`9`.

Constant:
`2`

Explanation:

"Like terms" are terms whose variables (and their exponents such as the
`2` in
`x^2`) are the same. In other words, terms that are "like" each other.Example:
`3x`,
`4x`, and
`7x` are like terms because they all have
`x`.

Coefficients are a number used to multiply a variable. In the above example, the coefficients would be
`3`,
`4`, and
`7`. In your problem, they're
`3` and
`9`.

Constants are numbers not attached to variables. See the diagram attached.
