So you need to add 6n with +2 then 5-7
It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them.
Answer:
A/2 - L = W
Step-by-step explanation:
A=2(L+W)
Divide each side by 2
A/2=2/2(L+W)
A/2=(L+W)
Subtract L
A/2 - L = L+W-L
A/2 - L = W
