Please help me answer the question.

Answer 1

The value of x=63, since the second figure is being multiplied by a scale factor of 9 to get the first figure. You can multiply 7 by 9 to get 63, therefore being the length of side x.

Answer 2

63

Explanation:

Each side is bigger by a factor of 9, i.e. 10*9=90, etc.

so 7 * 9 = 63
