Answer 1

so the perimeter is 2x + 40 soo Notice that 2x + 40 is part of the expression.
A fence all around the farm is 2x + 40 feet long.
He already put up 30 feet of fencing. so he still needs to put up 2x + 10 of the fencing

Answer 2

if you start with 2x + 40, what do you do with 30 to end up with
(2x + 40) - 30?

Answer 3

A. The unfenced length of the fence.
B. The perimeter length of the farms boundary.

Answer 4

2x + 40) - 30 represents 30 subtracted from 2x + 40.

Since 2x + 40 is the perimeter of the farm, the fence needs to be 2x + 40 feet long.
He already fenced 30 ft, so he has (2x + 40) - 30 ft of fencing left to do.

Answer 5

soo x is the width. 2x is the sum of the two widths.

Answer 6

A. the amount of fencing left to do
B. the perimeter of the farm
C. the sum of the two widths
