Subtracting from a number means removing from a term.

So we set it up as (4a+16)-(a-4)

Now we distribute the - to a and -4.

So now it is 4a+16-a+4

Combine the like terms to get 4a-a+16+4

So your answer is 3a+20

Subtracting a-4 from 4a+16 and then simplifying the expression will be 3a + 20.

This is a simple expression and we have to subtract a-4 from 4a+16 and then simplify the answer. This will be:

(4a + 16) - (a - 4)

= 4a - a + 16 + 4

= 3a + 20

In conclusion, based on the calculation above, the answer is 3a + 20.
