If l = 2(w + 1), which of the following correctly gives w in terms of l?

Answer?

Or  

(both are correct - just different ways of writing the equation)

Step-by-step explanation:

Expand the bracket:

Subtract 2 from both sides:  

Divide both sides by 2:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
