When writing an expression in expanded form, we just need to multiply what's outside the parentheses by everything that is inside the parentheses.
5a (6b + 12)
(5a * 6b) + (5a * 12)
30ab + 60a
And that is our answer.
5a (6b + 12) in expanded form is 30ab + 60a.

Let q be the number of 25 cent coins.
Let d be the number of 10 cent coins.
0.25q+0.10d= 3.95...(1)
q-d=6...(2)
(2)-> q-d= 6
q-d+d= 6+d
q= 6+d...(2a)
(2a)-> (1) 0.25q+0.10d=3.95
0.25(6+d)=0.10d= 3.95
1.95+0.25d+0.10d= 3.95
0.35d= 3.95-1.5
0.35d/0.35= 2.45/0.35
d= 7...(3)
(3)->(2) q-d= 6
q-7= 6
q=6+7
q= 13
There are 13 quarters and 7 dimes.
