Answer 1

so im looking for number that will equal 512

Answer 2

i get 3.5

Answer 3

wel 3.6 isnt an option

Answer 7

yw

Answer 8

6 5/9 is another option and 12 and 18 which i dont even look at so either of of those two fractions

Answer 9

If two polygons are similar, the square of the scale factor of the two polygons is equal to the ratio of the areas of the polygon.
That said, the square of the ratio of x to 8 is equal to the ratio of the areas of the similar polygons.
64/144 = (x/8)^2
8/12 = x/8
2/3 = x/8
3x = 16
x = 16/3 = 5 1/3

Answer 10

that means im not that off thank you

Answer 11

I overlooked that area part. I was thinking perimeter.
