Answer:
A, E
Step-by-step explanation:
Wanted expression: 6(b+2)-b
Let's factorise each expression and make it look like the wanted expression as much as possible.
A: 5b+12
In this case we do not have a "-b" at the back, to make it similar to the given expression we can insert a "-b" at the back while adding 1 b to the front (5b) of the expression.
6b+12-b
6(b+2)-b
B: 7b+8
8b+8-b
8(b+1)-b
C: 6b+8-b
2(3b+4)-b
D: 5b+8
6b+8-b
2(3b+4)-b
E: 6b+12-b
6(b+2)-b
The 2 expressions out of A-E that are the same as the wanted expression are A and E.
hope this helps :))
