(-3+5)(1) = -3+5i
(-3++5) =-16-30/
(-3+5)(3-5) = 16+301

i dont know

step-by-step explanation:

$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

just sum

10 + 10 = 20
