Find the degree of the following polynomial 12c^5d^4+9c^3d^9-7

12

Step-by-step explanation:

The degree of a polynomial is the great sum of the exponents in one term. Terms are not separated by addition or subtraction.

The terms are:

12c⁵d⁴

9c³d⁹

- 7

Add the total value of the exponents in each of the terms:

12c⁵d⁴: 5+4=9

9c³d⁹: 3+9 = 12

- 7 : Sum is 0 because there are no exponents.

Choose the greatest sum of a term: 0, 9 or 12?

The degree is 12 because it is greater than 9 and 0.
