Answer: 1st one : degree = 5; number of terms = 3
2nd one: degree = 6; number of terms = 4
3rd one: degree = 4; number of terms = 2
Step-by-step explanation: First you have to simplify everything.
So for the first one you would get 14x^5 -30x^4 + 2x^3; After that you just say that the degree is 5, and number of terms is 3. For the second one you do the same thing; simplify and then find the degree and number of terms. If your confused on how to simplify then look at the work that I've showed below (my work) And if your confused on how to find the degree, it's just what term has the highest power, to be more clear lets say we have x^3 + x^4*y^7. We have 2 terms, and the degree of the 1st is 3, and the degree of the second term is 11. Meaning the degree of the polynomial is 11 (the larger one) If your confused on how to find the amount of terms, then it's just counting them, they're divided by subtraction and addition.
