Answer 2

It was a little hard to visualize. I think this is what they mean

Answer 3

I suppose they want a scale factor or something along those lines

Answer 4

I think the height's 9.5 and they want the length.
and the triangles are similar so we can set up an equation

Answer 5

Hi

Answer 6

corresponding sides are proportional so
\[\frac{ 12 }{ x }=\frac{ 8 }{ 9.5 }\]

Answer 7

So then we cross multiply and solve, right

Answer 8

144 = 8x, x = 18

Answer 9

12*9.5 = 114
