radius = (4*10^2 + 24^2)/8*10 =
(400 + 576)/80=
976/80 = 12.2
diameter = 12.2 x 2 = 24.4
First factor the numerator
b^2-6b+8/b-4 * b+8/b-2
u will get
(b-2)(b-4)/(b-4)*(b-2)*b+8
those will cancel out each other will left only
b+8<span />
Answer:
it will be 20$ if im wrong you can correct me
1. plug in the numbers for the variables, like this: 9(-5)+18(-1)
2. solve
Hopefully this helps! Let me know if you need more explanation.
Step-by-step explanation:
8 because 24 ÷3=8 so yeah
