-16 + 3n = -(8 + 5n)
The - sign outside the parentheses acts as a -1, and so it is distributed to each term in the parentheses.
-16 + 3n = -8 - 5n
+16
3n = 8 - 5n
+5n
8n = 8
/8
n = 1
Let's say the speed of the plane is "p", and the speed of the wind is "w".
when the plane goes with the wind, is not really going "p" mph fast, is really going "p + w" mph fast, because the wind is adding speed to it.
likewise when the plane is going against the wind, is also not going "p" fast is going "p - w" mph fast. Therefore,

Answer:
Step-by-step explanation:
Well first you have to find the dimensions of the frame, you can find that by subtracting the dimensions of the photo from the whole dimensions so it will be the

Now the width of the photo and frame - width of the photo = 20 -16 = 4 the width of the frame
ok so the Area of the rectangle = width x length = 4 x 5 = 20 the Area of the frame
