Which pair of expressions is equivalent? a. 15a + 6 and 3(5a +3) b. 14b +4 and 2(7b -2) c. 5(2c +3) and 7c + 8d. 3(d + 5/3) and 3d + 5

Step-by-step explanation:

Two expression are called equivalent if after simplifying them we get same expression,

In option a :

By using distributive property,

3(5a + 3) = 3(5a) + 3(3) = 15a + 9 ≠ 15a + 6

In option b :

2(7b-2) = 2(7b) - 2(2) = 14b - 4 ≠ 14b + 4

In option c :

5(2c+3) = 5(2c) + 5(3) = 10c + 15 ≠ 7c + 8d,

In option d :

Hence, OPTION d has the pair of equivalent expression.

i think asking google will you get the answer to that question
