Answer:
3(x + 6) and 4x + 18 - x
Step-by-step explanation:
Let's solve each option to see whether we would get 3x + 18:
✔️2x + 9 + 2x + 9
Add like terms
2x + 2x + 9 + 9
4x + 18
✔️3(x + 6)
3*x + 3*6
3x + 18 (it is an equivalent)
✔️4x + 18 - x
Add like terms
4x - x + 18
3x + 18 (it is an equivalent)
✔️2(4x + 9)
8x + 18
Therefore, the expressions 3(x + 6) and 4x + 18 - x are equivalent to 3x + 18

Answer:
8 is the radius.
Step-by-step explanation:
The standard form of a circle is 
.
However, I like to call it center-radius form because it tells us the center and the radius.
The center is 
and the radius is 
.
So your equation is 
.
So the center for this circle is (0,0) and the radius is 8.
If it wasn't so obvious that 
is 64 then you could have entered 
in your calculator to get 8.
