What did you get for Part A?

anonymous · Answer

5.5. I evaluated geometrically  for x=1-2, 2-4, and 4-7.

tkhunny · Answer

You did not answer my question.  What was your result?

anonymous · Answer

It was 5.5

anonymous · Answer

Try looking at it again, I got 8 for part A.

tkhunny · Answer

Okay, now is the time to go back and figure out why you did not get 8.

What were your intermediate results?

x=1-2 ==> ?
x=2-4 ==> ?
x=4-7 ==> ?

anonymous · Answer

1-2=1.5
2-4=1
4-7= 3

tkhunny · Answer

1-2  ==> Trapezoid: (1/2)(3+1) = 2
See if you can improve the second one.

anonymous · Answer

Oh! I evaluated as triangles. So for 2-4 would you suggest splitting it into two?
