Ranger says the expression is not in its simplest form. He thinks the two terms need to be combined. Is Ranger right that 8x − 20 can be simplified further? Provide support for your response.

Respuesta :

Ranger is incorrect. The expression, 8x – 20, is in its simplest form because there are no parentheses and no like terms. The two terms cannot be combined because only one term has x as its variable.

Like expressions can be simplified.

Ranger's claim is incorrect.

The expression is given as:

[tex]\mathbf{8x - 20}[/tex]

8x and 20 are not like terms, because:

  • 8x has a coefficient of 8 and a variable x
  • 20 is just a constant

A constant and a variable cannot be added or subtracted.

This means that:

[tex]\mathbf{8x - 20}[/tex] is already in its simplest form, and it cannot be further simplified.

Hence, Ranger is incorrect.
