which are correct

5a ^ 2 * b - 6a * b ^ 3 * c + 3a ^ 5 is a fifth degree polynomial.

5a ^ 2 * b - 6a * b ^ 3 * c + 3a ^ 5 has a leading term of 5.

5a ^ 2 * b - 6a * b ^ 3 * c + 3a ^ 5 contains three terms.

12x - 10x ^ 5 - 7 + 3x ^ 4 is equivalent to - 10x ^ 5 + 3x ^ 4 + 12x - 7

12x - 10x ^ 5 - 7 + 3x ^ 4 has a leading term of - 10x ^ 5 .

12x - 10x ^ 5 - 7 + 3x ^ 4 has a leading coefficient of 12.

All of the statements are correct.

5a^2 * b - 6a * b^3 * c + 3a^5 is a fifth degree polynomial because the highest power of a in any term is 5.

5a^2 * b - 6a * b^3 * c + 3a^5 has a leading term of 5a^2 * b because it has the highest power of a and the highest power of b.

5a^2 * b - 6a * b^3 * c + 3a^5 contains three terms: 5a^2 * b, -6a * b^3 * c, and 3a^5.

12x - 10x^5 - 7 + 3x^4 is equivalent to -10x^5 + 3x^4 + 12x - 7 because the terms have been rearranged.

12x - 10x^5 - 7 + 3x^4 has a leading term of -10x^5 because it has the highest power of x.

12x - 10x^5 - 7 + 3x^4 has a leading coefficient of 12 because it is the coefficient of the highest power term.
