Which expression has a negative value? a) b)−1×2×−3×4×−5 c)1×−2×−3×−4×−5 d)1×−2×3×−4×5

B

Step-by-step explanation:

B) -1*2*-3*4*-5=-2*-3*4*-5=6*4*-5=24*-5=-120

C) 1*-2*-3*-4*-5=-2*-3*-4*-5=6*-4*-5=-24*-5=120

D) 1*-2*3*-4*5=-2*3*-4*5=-6*-4*5=24*5=120

$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
