A. find and explain the error in the work shown. b. fix the error and show work with the correct result.

Well, first they're assuming that the m<ABC = 90

The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.

It is given that BD bisects <ABC, which means it splits the angle evenly..

Giving this equation: (x-5) = (2x-6)

Solving for x  

-5 + 6 = 2x - x

1 = x

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
