Answer:

1  = 1m
2. -6x
3. -6a+b
4. 5ao
5. -6b^3

Step-by-step explanation:

Natariiiiiiiigo

1. 2m + (-3m)

↓ determine the sign

2m - 3m

↓ combine like terms

-m

2. -5x + (-x)

↓ determine the sign

-5x - x

↓ combine like terms

-6x

3. -6a - (-b)

↓ determine the sign

-6a + b

4. (5a) (o)

↓

5a × o

↓ multiply 5a by o

5ao

5. (-6b) (b²)

↓

-6b × b²

↓ multiply the monomials

-6b³

Note:

  • A monomials is a real number, a variable or a product of a real number and variables raised to whole number powers. some examples of monomials are: -2 (real numbers), x (variable), etc..

  • the degree of a monomial is the sum of the exponents of the variable in the monomial.

  • A monomial is a polynomial

  • To multiply a polynomial by a monomial, use the distributive property
