Answer:
23h^2
Step-by-step explanation:
These are all like terms so we add/subtract them from left to right.
7h^2+6h^2+5h^2+6h^2-h^2
= 24h^2 - h^2
= 23h^2 (answer)

Answer:
Our total amount value is $4.86.
Step-by-step explanation:
The total amount given is $30.
Now 8 % of $30 = 
or, 8% of $30 = $2.4
Now adding $30 and $2.4,
$ 30 + $2.4 = $32.4
Finding 15% of the total $32.4,
we get 
or, 15% of $32.4 = $4.86
hence, our total amount value is $4.86.
If two angles are supplementary, their sum equals 180 degrees
