a. 4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
b. 4(2a ⋅ 5) = 8a ⋅ 20
c. 4(2a ⋅ 5) = (2a ⋅ 5) ⋅ 4
d.4(2a ⋅ 5) = 4 ⋅ 2a ⋅ 5

Option A -

Step-by-step explanation:

Given : Pair of expressions.

A.

B.

C.

D.

To find : Which pair of expressions is equivalent using the Associative Property of Multiplication?

Solution :

Associative Property of Multiplication states that multiplication of group of numbers in any combination.

On comparison with property,

satisfy the condition.

Where, a=4, b=2a and c=5.

Therefore, Option A is correct.
