Answer: The distance around the lot is given by

Step-by-step explanation:
Since we have given that
Length of rectangular lot is given by

Width of rectangular lot is given by

We need to find the distance around the lot.
As we know the formula for "Perimeter of rectangle":

Hence, the distance around the lot is given by

Subtract these 2 equations,
5x-5x +3y-y = -4-6
2y = -10
y = -5
-5 is your answer.
Answer:
Carla has been running 7 miles each day for 13 days.
Step-by-step explanation:
Carla ran 3 miles on her first day, 5 miles on her second day and then 7 miles each day onward.
Let the number of days she ran 7 miles each day = x
Total distance run by Carla = 3 + 5 + 7(x)
= 8 + 7x
If her log book shows that she has run total distance = 99 miles
Equation representing her total run will be,
8 + 7x = 99
7x = 99 - 8
7x = 91
x = 
x = 13 days
Therefore, Carla has been running 7 miles each day for 13 days.
