To solve this problem, we need to first find the sum of the two polynomials and then determine the number of terms (binomial or trinomial) and the degree of the resulting polynomial.

Given polynomials:

1. $6s^2t - 2st^2$
2. $4s^2t - 3st^2$

Step 1: Add the two polynomials

To find the sum, add the corresponding terms:

$(6s^2t - 2st^2) + (4s^2t - 3st^2)$

Combine like terms:

$(6s^2t + 4s^2t) + (-2st^2 - 3st^2) = 10s^2t - 5st^2$

Step 2: Determine the number of terms and the degree

• The resulting polynomial is $10s^2t - 5st^2$.
• This polynomial has two terms (making it a binomial).
• The degree of each term:
  • $10s^2t$ has a degree of $2 + 1 = 3$.
  • $-5st^2$ has a degree of $1 + 2 = 3$.

Conclusion:

• The sum is a binomial with a degree of 3.

Therefore, the correct statement is: The sum is a binomial with a degree of 3.
