Which expressions are equivalent ? A. 3v+5-9v+2 and 6v+6 B. -6n+3-2n+2 and -8n+6 C. -4n+8+9n-2 and 5n+6 D. 10n-5-2n+3 and 5n-2

  C.  -4n+8+9n-2 and 5n+6

Step-by-step explanation:

The equivalent expression is found by combining like terms:

  -4n +8 +9n -2 = n(-4+9) +(8-2)

  -4n +8 +9n -2 = 5n +6 . . . . . matches choice C

__

The other answer choices have flaws in the work:

  A. 3v -9v ≠ 6v

  B. +3 +2 ≠ +6

  D. 10n -2n ≠ 5n

C. -4n+8+9n-2 and 5n+6
