Answer:
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
Answer:
11 inches
Step-by-step explanation:
Let the level of ground level be g
On first day, amount of snow melted by 3 inches
So, level of ground melted= (g- 3) inches
Next day, amount of snow melted by 8 inches
So, level of ground level melted = (g- 3-8 )inches
Hence, total change in the ground level = ( g- 11) inches
Hence, amount of snow on ground level melted by 11 inches
Hence, the correct answer is 11 inches
