Chelsea has 55 art brushes. She has this manu because Monique has 5 necause 11x5 is 55. 55 plus Monique's 5 is 60 brushes in total. Have a nice day :)
Remember to incorporate Bimdas, into you calculation and ensure where the addition and subtraction occur you work from left to right.
To determine the degree of a polynomial, you look at every term:
- if the term involves only one variable, the degree of that term is the exponent of the variable
- if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.
So, for example, the degree of
is 55, while the degree of
is 
Finally, the term of the degree of the polynomial is the highest degree among its terms.
So,
is a degree 2 polynomial (although it only has one term)
similarly,
is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.
