To match the numbers to the letters for the equivalents, we can simplify each expression:
3(4x + 2) = 12x + 6 (A)
(2x + 3) - (4x + 5) = 2x + 3 - 4x - 5 = -2x - 2 (B)
8x + 5 - x + 4 = 8x - x + 5 + 4 = 7x + 9 (C)
7(3x - 2) = 21x - 14 (D)
Matching the numbers to the letters for the equivalents:
Expression 1 is equivalent to option A.
Expression 2 is equivalent to option B.
Expression 3 is equivalent to option C.
Expression 4 is equivalent to option D.
