Reset the password to something secure not abc123 or something like that for sure and if it continues I would just delete it and make a new one good luck!
The place value is the tenths place
So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2
The colution to your problem is a. (3,-6)
