Step-by-step explanation:
Answer:
119.32 m
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
C = 2 (3.14) *19
C = 119.32
A(x) = 3x - 12
b(x) = x - 9
a(b(x)) = a(x - 9) = 3(x - 9) - 12 = 3x - 27 - 12 = 3x - 39
a(b(x)) = 3x - 39
4.2 the 2 is in the tenths place so you round it using the 3 because it is the first one behind it and 3 is less than 5 so it just stays at 2 so your answer is 4.2
F=2+b

f-12=2(b-12)
f=2+b
2+b-12=2(b-12)
b-10=2b-24
minus b both sides
-10=b-24
add24
14=b
14-12=2
2+2=4
freddy was 4 and brother was 2
