Answer:
A
Step-by-step explanation:
Dimension of the rectangular fence:
Length = 30 ft
Width = 25 ft
Perimeter of the rectangular fence = 2(L + W)
= 2(30 + 25) = 2(55)
Perimeter = 110 ft
Fencing cost per foot = $4.05
Fencing cost for 110 ft = 110 × 4.05 = $445.50

Step-by-step explanation:
4x+5-2x+1=2x-5
(4x-2x)+(5+1)=2x-5
2x+6=2x-5
2x=2x-11
2x-2x=-11
0=-11 no solution
