We're doing a review this week and i'm already having problems. I dont remeber doing this problem and cannot find similar problems in the book. Here's the question:(adsbygoogle = window.adsbygoogle || []).push({});

You are given the three points in the plane [tex]A= (6-3)[/tex], [tex]B = (11,8)[/tex], and [tex]C=(15,0)[/tex]. The graph of the function [tex]f(x)[/tex] consists of the two line segments [tex]AB[/tex] and [tex]BC[/tex]. Find the integral [tex]\int_6^{15} f(x)dx[/tex] by interpreting the integral in terms of sums and/or differences of areas of elementary figures.

1.) [tex]\int_6^{15} f(x)dx[/tex] = _______

Here's what i done:

the first thing i did was plugged in A,B, & C points into a graph. after that, i connected the dots and found out that there were two triangles. So i used the area of the triangle formula to find the area of each triangles and added it together. I got an answer of 43.5, but it's incorrect. I'm not good at math, so can someone point me to the right direction?
