Simplify: (3x2 − 4xy + 7y2) − (7x2 − 6xy − 3y2) −4x2 − 10xy − 10y2 −4x2 − 2xy + 10y2 −4x2 − 10xy + 10y2 −4x2 + 2xy + 10y2

its kind of blurry. can you put a clearer pic?

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

or

its line 2 i just added the rest or else it wouldn't let me answer
