Answer:
20x+6
Step-by-step explanation:
The perimeter is
P= 2l + 2w
P = 2( 8x-1) + 2(2x+4)
Distribute
= 16x-2 + 4x+8
Combine like terms
= 20x+6
In 7 hours 644 newpapers
in one hour it is 644/7= 92
in 9 hours-> 92x9 =828 newspapers
12 ft I think because 18 would be too long

I would say the answer is A
