2 * plane speed in still air = 289mph + 257mph = 546
plane speed in still air = 273 mph
plane speed in still air + wind speed = 289
273 + wind speed = 289
Therefore, wind speed = 16 mph

Answer:
Step-by-stepapex answer to the left of 9.9 and to the right of 9.3 explanation:
Answer:
- 288
Step-by-step explanation:
The n th term of a geometric series is
= a
- 144 
is in this form
with a = - 144 and r = 
= 
= 
= 
= - 288
(Since the perimeter is the length of each sides added up. Two sides are equal to x+6 and two are equal to x-6)
2 (x+6) + 2 (x-6) = 48
(break out the brackets)
2x + 12 + 2x -12 = 48
( 12 and -12 cancel out and "disappear".)
2x + 2x = 48
4x = 48
(Rearrange for x)
x = 48 / 4
x = 12 inches
