You can proceed like this,
650 kb for a pic
and 2200kb for song ( 650 + 1550)
total= 18150 kb and 16 files
so, 650 kb each in both pic and song = 16 * 650= 10400
remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5
so, a total of 5 songs and 11 pictures were sold..
hope it helped

Answer:
105
Step-by-step explanation:
f(x) = 8x² + x -9
g(x) =5x²
(f+g)(x) = 8x² + x - 9 + 5x²
Collect like terms
8x² +5x² + x - 9
13x² + x - 9
b) (f+g)(-3) = 13x² + x - 9 when x =-3
= 13×-3² + (-3) - 9
= (13×9) -3 -9
= 117 -3 -9
= 105
