Answer:
b=9
x=5.5
Step-by-step explanation:
find the common ration
AB is 6, and XY is 3 (they are the corresponding sides)
ratio is 2 to 1 (6/3=2/1)
AC corresponds with YZ
XY is 4.5 so b is 4.5*2=9
ZY corresponds with CB
CB is 11, since XYZ is the smaller divide by 2 instead of multiplying by 2
-.425 divide the top number by the bottom number :)
Distribute the 2 then do your loop.
5^3 = 2x+16
Then you can solve for x.
If f(x)=2x-1 just plug in the 3 where x is. So it would be 2(3)-1=5
