1. The formula for calculate the perimeter of a rectangle, is:
P=2L+2W
P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.

2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W
3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:
P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet
4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:
x=P-W
x=320 feet-40 feet
x=280 feet

How many linear feet of fence must he buy?

The answer is: 280 feet
The area of a hexagon is
A= a^2 (3√3)/2
we replace a with 4
A=41.57
Answer: 32.67
Explanation: Use multiplication to get this answer, and a basic hint is the word "of", that's a word in Mathematics for multiplying.
Answer:
y = -1/3x - 5 1/3
Step-by-step explanation:
Slope Intercept =
y=mx + b
Substitute the Slope
y= -1/3x + b
Substitute x and y from the point into the equation
-6 = -1/3(2) + b
-6 = -2/3 +b
Isolate the b with the addition property of equality
-5 1/3 = b
Substitute all variables
y = -1/3x - 5 1/3
