Subtract the polynomials (7.8x - 3.4y + z) and (-9.2x + 4.8y - 2.1z), then place the answer in the proper location on the grid. write answer in x-y-z order and include the tenths place.

Step-by-step explanation:

We are given that two polynomials

(7.8x-3.4y+z) and (-9.2x+4.8y-2.1z)[/tex]

We have to subtract the polynomials.

Open the bracket

Rearrange the terms

Combine like terms

Hence, the answer is given  by

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above
