Answer:
82
Step-by-step explanation:
f(x) = 5x - 3
g(x) = 2x + 9
f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)
f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82
The unit of measurement appropriate for this would be meters^2
a.c=2πr
c=2x3.142x50
c=100x3.142
c=0.03142
b.c=2πr
286=2x31/7xr
286=62r/7
286x7=62r
2002=62r
2002/62=r
32.3=r
r=32.3
2 out of 6
3; all real numbers except x = 2
