Answer: D. 3(d + [tex]\frac{5}{3}[/tex]) and 3d + 5

Step-by-step explanation:

       We will distribute and simplify the expressions to find which pair is equivalent. In other words, which pair is equal.

✗ [A] 3(5a + 3) = 15a + 9 ≠ 15a + 6

✗ [B] 2(7b - 2) = 14b - 4 ≠ 14b + 4

✗ [C] 5(2c + 3) = 10c + 15 ≠ 7c + 8

✓ [D] 3(d + [tex]\frac{5}{3}[/tex]) = 3d + 5 = 3d + 5

       3d + 5 = 3d + 5, which means option D is the answer to our question.
