:( sorry idk to this question
The x= the cut for the grass
The y=garvin cuts
348=20x+18y
132=18+x
<span>the perimeter of the cross section is 16.5 inches.
the perimeter of the cross section is 2*L plus 2*W where L is the length of the cross section and W is the width of the cross section.
since L = 2*W, the perimeter becomes 4*W plus 2*W = 6*W.
16.5 / 6 = 2.75 inches.
W = 2.75 inches.
L = 5.5 inches.
P = 2*L + 2*W = 2*5.5 + 2*2.75 = 11 + 5.5 = 16.5 </span>
A. -3(-1) + 7 = 4
3 + 7 = 4
11 = 4 (wrong)
B. 4x - 8 = 12
4(-1) - 8 = 12
-4 - 8 = 12
-12 = 12 (wrong)
C. -2x + 3 = 1
-2(-1) + 3 = 1
2 + 3 = 1
5 = 1 (wrong)
D. 8x + 5 = -3
8(-1) + 5 = -3
-8 + 5 = -3
-3 = -3 (correct!)
So, in conclusion, D is the correct answer.
There are 599 people on the tenth night and 4111 if you add all the nights together.
