1st step would be to combine like terms so you would have
4p-7 = 13
A*2 + b* = c*2
(9)*2 + (8)*2
81+64= 145
145=c*2
12.04=c
Answer:
The perimeter of the dog run will use 67.2 feet of fencing.
Step-by-step explanation:
First find how long the width is.
24 * 2/5 = 9.6
The width of the fence is 9.6 feet.
To find the total perimeter, add double the length and width.
24 * 2 = 48
9.6 * 2 = 19.2
48 + 19.2 = 67.2
515 - 87 = 428
428/245 = 1.746938
To the nearest tenth = 1.7 lbs
Can you tell us what the expression is in the question?
