Answer:
Option (a) and (d) are correct .
An equivalent expression to the given expression 2(4f + 2g) is 8f + 4g
and 4 (2f + g)
Step-by-step explanation:
Given: Expression 2(4f + 2g)
We have to choose an equivalent expression to the given expression 2(4f + 2g)
Consider the given expression 2(4f + 2g)
Apply Distributive property, 
We have,
a = 2, b = 4f and c = 2g
2(4f + 2g) = 8f + 4g
Now, take 4 common from each term, we have,
8f + 4f = 4 (2f + g)
Thus, an equivalent expression to the given expression 2(4f + 2g) is 8f + 4g and 4 (2f + g)
