P² - r²
subtitute p =10 and r= -4
10² - (-4)² = 100 - 16 = 84
the zeros will be 2+√3 and 2-√3
15.34/0.59 = 26 songs bought
28 free songs
so...
26+28 = 54 songs in total
Hope this helps :)
Step-by-step explanation:
f(2) = 4(2) - 2
= 8 - 2
= 6
g(f(2)) = g(6)
g(6) = 5(6) - 3
= 30 - 3
= 27
g(f(2)) = 27
