anonymous · Answer

could you possibly walk my daughter through how you got that,, im not to good at math and shes not understanding what you mean? sorry its confusing to us. lol

anonymous · Answer

4d+9d-(7-6d) = 4d+9d-7+6d = 4d+9d+6d-7 = 19d - 7

anonymous · Answer

Do you see the negative sign before the bracket?
To make it simpler put a -1 in front:4d+9d-1(7+6d)
Now you gotta do distribution
4d+9d-1*7-1*-6d
Now simplify:  4d+9d-7+6d
19d-7
