Sorry But I can't understand what − means so i will solve this for x+3 and x-3
first for x+3
equation e= x(x+3)(x+4)>0
so points are x= 0,-3,-4
for range x<-4
e<0
for -4<x<-3
e>0
for -3<x<0
e<0
and for x>0
e>0
so the interval when e>0
x â (-4<x<-3 and x>0)
now for x-3
equation e=x(x-3)(x+4)>0
so points are x= 0,3,-4
for range x<-4
e<0
for -4<x<0
e>0
for 0<x<3
e<0
and for x>3
e>0
so the interval when e>0
x â (-4<x<0 and x>3)
Problem 44
The term "bisect" means "cut in half".
Since BD bisects angle ABC, this means the smaller angles ABD and DBC are congruent.
angle ABD = angle DBC
x+15 = 4x-45
15+45 = 4x-x
60 = 3x
3x = 60
x = 60/3
x = 20
<h3>Answer: x = 20</h3>
========================================================
Problem 45
We use the same idea as the previous problem
angle ABD = angle DBC
2x+35 = 5x-22
35+22 = 5x-2x
57 = 3x
3x = 57
x = 57/3
x = 19
<h3>Answer: x = 19</h3>
