• 3x^4

• x

• 4x + 10

• 12y - 7x

Answer explanation

A monomial is one term! Meaning there is no addition/subtraction signs.

Select all polynomials (they include monomials)

• 8

• 15y^2

• 9x^2 - 15x + 30

• 8y - 100

• 48

• 95

• -28

Answer explanation

The degree of a monomial is the same thing as the power on the variable.

• 20x^5 + 5x^4 + 3x^2 - 10x^8

• 3x^2 + 5x^4 + 20x^5 - 10x^8

• 20x^5 - 10x^8 + 5x^4 + 3x^2

• -10x^8 +20x^5 + 5x^4 + 3x^2

Answer explanation

Descending order meaning starting with the biggest degree and going down. Numbers by themselves have a degree of 0!

• 4x^3

• -4x^3

• -4

• -4x
