Answer:
1.b(8-4)= b(4) = 4b
2. b(2+2)= b(4) = 4b
3. b(6-2)=b(4)=4b
Explanation:
This problem bothers on our understanding of algebraic expression and its equivalent
4b is such an expression
To find it equivalent we have
Say
1.b(8-4)= b(4) = 4b
2. b(2+2)= b(4) = 4b
3. b(6-2)=b(4)=4b
We can go on and on. The list is endless so long as we the right factors of 4 under check.
The best way to get a hold on this is to understand your factors very well
