Sagot :
Answer:
B. 4
Step-by-step explanation:
You need to check on which term has the highest degree. To check the degree of a term, you need to add the exponents of each variable
1st term - 3(x^2)(y^2)
2+2 = 4th degree
2nd term - -(x^2)(y)
2+1 = 3rd degree
Note: Exponent of y is 1.
3rd term - (x)(y)
1+1 = 2nd degree
Note: Exponent of both x and y is 1
Last/4th term - -65
0+0 = 0
Note: Exponent of both x and y is 0
