Answer:
First one: Degree of 13, type monomial
Second one: Degree of 5, type trinomial
Third one: Degree of 8, type trinomial
Step-by-step explanation:
The degree of a polynomial is determined by the highest degree of its individual terms. To determine the degree of a term, add up the power values of the variables.
The type of the polynomial is determined by how many terms are being separated by an addition sign ( a subtraction sign is just the addition of the inverse of a number).
One term: Monomial
Two terms: Binomial
Three terms: Trinomial
Four terms and so on: Generally just called polynomials
Steps to solve:
3 + x(-2) = 10
~Simplify
3 - 2x = 10
~Subtract 3 to both sides
-2x = 7
~Divide -2 to both sides
x = -3.5
Best of Luck!
