Answer: The correct option is
(A) -22z.
Step-by-step explanation: We are given to simplify the following expression :
[tex]E=-8z-14z~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To simplify the given expression, we should combine the coefficients of z.
The simplification of expression (i) is as follows :
[tex]E\\\\=-8z-14z\\\\=(-8-14)z\\\\=(-22)z\\\\=-22z.[/tex]
Thus, the required simplified form is -22z.
Option (A) is CORRECT.
