Depends on where the underline is
Answer:
7
Step-by-step explanation:
1) 8
2) 14.5*2=29
3) 7x+5=2*13, 7x+5=26, 7x=21, x=3
4)d(1)=2r,
if r increase 3 times, d(2)=2*(3r)
d(2)/d(1)=(2*3r)/2r=3,
so diameter increases 3 times
Idk if this is the right answer. But I think it is.
15x3=45
45+7=52
208-52=156
