Answer:
degree 3
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of the term within the polynomial.
4x²y = 4x² ← with exponent 2 + 1 = 3
x² ← exponent 2
- 2y² ← exponent 2
The term with the largest exponent is 4x²y with exponent 3
Then the polynomial is of degree 3
Answer:

Answer:
15 times the first equation and -12 times the second equation
Step-by-step explanation:
we have
------> first equation
------> second equation

-----> new first equation
Multiply the second equation by -12 both sides
-----> new second equation
Adds the two new equations
