It would help a lot if you could give step by step directions.

47 - 90 = 43

43 - 180 = x

x = 137

it is 10.6 according to my calculations

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
