Help please if you can thanks

A. 8

Step-by-step explanation:

1kg=2.2

18.5 lbs= 8kg

  The answer is 8

Step-by-step explanation:

Not sure how to explain it but after a while of adding the kg it will be 8.39145885 kg, if your round it, the answer will be 8.  Hopefully it helps.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
