oh wow! No wonder I could not figure out what I was doing :/ One question though, my answer choices are 1, -1, 2 and -1/2

Could it be positive 2 instead of -2?

I think the answer is 2.369 using a scale factor of 1.333 not sure though

We let x be the unknown scale size that is given as "question mark" in the item. We use the geometric mean concept to answer. The equation that would best describe the given is,
                 2.618(x²) = 1
The value of x from the equation is 0.618. 

I need help with same question but the website you gave didn't make any sense to me or show me how to solve..?

can anyone help answers these?
