Barbara used the distributive property to write an expression that is equivalent to 7 d + 63. Her work is shown below.
The greatest common factor is 7 so 7 d + 63 = 7 (d + 63)
What was Barbara’s error?
Barbara wrote (d + 63) instead of 63 d).
Barbara wrote (d + 63) instead of (d + 9).
Barbara wrote (d + 63) instead of (d + 56).
Barbara wrote (d + 63) instead of (10 d).

Answer:
option B is correct.
Step-by-step explanation:
because if 7 is the hcf then,
7d/7 = d and
63/7 = 9.
hence it should be 7d + 63 = 7 (d+9).
