Step-by-step explanation:
We have,
− 3( x + 1)
= − 3x - 3
A. - 3x + (-3)
= − 3x - 3, is equivalent to − 3( x + 1).
B. x - 3
= x - 3, is not equivalent to − 3( x + 1).
C. - 3x + 1
= - 3x + 1, is not equivalent to − 3( x + 1).
D. - 3x - 3
= - 3x - 3, is equivalent to − 3( x + 1).
Thus, A) - 3x + (- 3) and D) - 3x - 3 are equivalent.
