Answer:
<em>14</em>
Step-by-step explanation:
20=2(x-4)
therefore, x=14
The equation to find a spheres surface area is 4 pi R ^2
and this works in any order
4 * 12 is 48 (4 * R)
48^2 is 2304 ((4 * R)^2)
the exact answer is 2304
the full answer is 7234.56 (((4 * R)^2)
)
The answer is y=-(2)^x + 3
Y<3 because the equation is adding 3 at the end.
