Would equal 12 if the parenthesis indeed equal the absolute value of -6 which is simply 6. 6 x 2 = 12. When you multiply by a negative number, it negates the answer, so -6 x 2 would be -12.
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
