Find the product. ( 4 5 )( 9 5 )(− 1 2 )

Find the product.

(5)(−9)(−2)

A)−63  

B)−90  

C)72  

D)90  

E)−84

the correct answer is D).90

$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
