What the problem is trying to show you, is that a positive number undoes a negative number and a negative number undoes a positive number meaning it changes it's value.
If I get 4 (positive number) and subtract it by 4 the answer will be 0 - the negative number -4 undid the number 4.
If I get -4 (negative number) and add 4 (positive number) the answer will be 0 - meaning the positive number 4 undid the number -4.
Hope it helped,

Answer:
perimeter: 22x-14
area : 24x^2-37x
Step-by-step explanation:
for perimeter, it is the length of all the sides added together
starting at the left and working clockwise
5x+((6x-7)-(3x+1))+2x+(3x+1)+(5x-2x)+(6x-7)
5x+6x-7-3x-1+2x+3x+1+5x-2x+6x-7
combine like terms
perimeter: 22x-14
for area, area of (5x*(6x-7)) and subrtact the missing portion of (2x*(3x+1))
(30x^2-35x)-(6x^2+2x)
area : 24x^2-37x
