Answer :
The expression would add 6d+7 and 10d+10.
So…
6d+7+10d+10
We add like terms which would be (7 and 10) and (6d and 10d)
7+10 is 17
6d+10d is 16d
So the answer would be
16d +17
So…
6d+7+10d+10
We add like terms which would be (7 and 10) and (6d and 10d)
7+10 is 17
6d+10d is 16d
So the answer would be
16d +17
