A square pyramid is shown. What is the surface area?

A square-based pyramid, with bases, labeled 3.5 centimeters and the side length of triangle labeled 7 centimeters.
(4 points)

19.25 cm2

30.625 cm2

49.625 cm2

61.25 cm2

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
