−2x2 − 5x + 3

Step-by-step explanation:

simplify

−4x2 + 10 + 2x2 −5x −7

= −4x2 + 10 + 2x2 + −5x +−7

combine like terms:

= −4x2 + 10 + 2x2 + −5x + −7

= (−4x2 + 2x2) + (−5x) + (10+ −7)

= −2x2 + −5x + 3

-2x^2-5x+3

Step-by-step explanation:

-4x^2+2x^2=-2x^2   10-7=3

$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
