I'm having problem trying to solve this question. Solve for x,8 is to 64 as 2 is to x, I need to know if this is the best answer (x-1)^2=64 (9-1)^2=64 (8)^2=64, is 64 the right answer yes or no.
No.
I answered this for you yesterday. What don't you understand about it?

8/64 = 2/x
multiply both sides by 64 x
8 x = 128
x = 16
To solve this problem, we can use the concept of proportions.
The given statement is: 8 is to 64 as 2 is to x. We can write this as the proportion:
8/64 = 2/x
To solve for x, we can cross multiply:
8x = 64 * 2
Simplifying the equation:
8x = 128
To isolate x, divide both sides of the equation by 8:
x = 128/8
Simplifying further:
x = 16
So, the value of x is 16, not 64. Therefore, (x-1)^2 = 16^2 = 256, not 64.
