The Quetion of an ellipse is X squared/ 49+ Y squared 81 /equals one the others is centered at the origin find the vertex is or the major axis and determine whether the ellipse is horizontal or vertical major axis

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450
