.70 * x = 9.1
.70/.70 * x = 9.1/.70
x = 13
It’s the first one because it has 7 rows and 7 columns which show that it is 7 times 7 or 7^2.
The next number would be 4 because you add 1, then, subtract 2, add 3, subtract 4, meaning you would add 5 to -1 and get 4
The answer is 4
The factor of 100x to the power of 2 power -9 is 2.
