I think you're having trouble because the equation you wrote for 8a has a slight typo.
The question says that the length is 9 less than twice the width. Your equation states the length is 9 times the width minus 2. So the length actually equals 2w – 9, meaning that w(2w – 9) = 180
Hope this helps! If you're still having trouble, let me know :)
6
think of this as the middle.
3 to the left to get to 3
And
3 to the right to get 9

The total distance will be 8685.2 kilo meters if she travelled by plane
Answer:
The answer to your question is 20 feet
Step-by-step explanation:
Data
A = (-2, 1)
B = (4, 1)
C = (-2, -3)
D = (4, -3)
Process
1.- Calculate the distance from C and D
dCD = 
dCD = 
dCD = 6
2.- Calculate the distance from A to C
dAC = 
dAC = 
dAC = 4
3.- Calculate the perimeter
Perimeter = 2(dCD) + 2(dAC)
-Substitution
Perimeter = 2(6) + 2(4)
-Simplification
Perimeter = 12 + 8
-Result
Perimeter = 20 ft
