<h2>Given:-</h2>
(x+9)(x−5)(x−8)<0
Let f(x)=(x−5)(x+9)(x−8)
Here the critical points are −9,5,8
- Plot these points on a number line. These points divide the number line into 4 intervals.
<h3>Now,</h3>
pick a point from each interval and find the sign of f(x)
Since the inequality given in the question is ′ < ′
the solution is the interval containing
′− ′ sign
Thus, x lies in the interval
<h3>(−∞ ,−9)∪(5,8)</h3>
Answer:
I think that answer is C i believe
20 should be the answer because 205 divided by 10 =20
