Answer:
I got x<equal to -11 or x>equal to4
Step-by-step explanation:
x^2+15x+44=0
(x+4)(x+11)=0(Factor left side of equation)
x+4=0 or x+11=0(Set factors equal to 0)
x=−4 or x=−11
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−11(Works in original inequality)
−11<x<−4(Doesn't work in original inequality)
x>−4(Works in original inequality)
Answer:
x<−11 or x>−4
X = 180 - 70 - ( 180 -120)
X = 180 - 70 - 60
X = 180 - 130
X = 50
By using porportions, such as the pythagorean therum (a squared plus b squared equals c squared) Good luck!
