Answer:
68 inches
Step-by-step explanation:
P = 2 (L + W)
P = 2(4x+5 + 4x+5)
P = 2(8x + 10)
P = 16x + 20
If x= 3
P = 16(3) + 20
P = 48 + 20
P = 68 inches
Answer:

Step-by-step explanation:
We are given the following in the question:
Controller cost = $135
System cost = $2.50 per foot of pipeline

Let the system requires F feet of pipeline.
Total cost will be given by the equation:

is the required expression for total cost
F: feet of pipeline required
c(F): Total cost of installation
