Ashley adds Polynomial A and B together:

Polynomial A: 5z + 4x^2 - 6y + 2

Polynomial B: 2x + 9y - 12z - 2

What will be the coefficients for x, y, and z in the resulting sum?

coefficient of x: 2

coefficient of y: 3

coefficient of z: -7

Step-by-step explanation:

To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.

The sum of the polynomials is:

A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2

A + B = 4x^2 + 2x + 3y - 7z

So, the coefficients are:

coefficient of x^2: 4

coefficient of x: 2

coefficient of y: 3

coefficient of z: -7
