It would be bigger than 1/2 inches because they are simply asking for the difference which is 5 1/2-5= 1/2.
The answers are 0 and 2
This can be found by looking at the x axis and finding every point where the line crosses
<span>A=1/2(a+b)h for h.
First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h
You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.
2A = (a + b)h
Now divide both sides by (a+b).
2A/(a+b) = h
