Answer:

Step-by-step explanation:

The inequality |4x + 2| < 26 can be rewritten into two inequalities as the |  | function can mean multiply by 1 or multiply by -1.

|4x + 2| < 26

= (4x + 2) < 26  or  -(4x + 2) < 26

= 4x < 26 - 2  or  -4x <26 + 2

= 4x < 24  or  -4x < 28

= x < 6  or  x > -7

Combining the two:

|4x + 2| < 26

= -7 < x < 6

The answer is C.
