Answer:
x≤−9 or x≥5 or x=0
Step-by-step explanation:
Let's solve your inequality step-by-step.
x2(x+9)(x−5)≥0
x4+4x3−45x2≥0
Let's find the critical points of the inequality.
x4+4x3−45x2=0
x2(x−5)(x+9)=0(Factor left side of equation)
x2=0 or x−5=0 or x+9=0(Set factors equal to 0)
x=0 or x=5 or x=−9
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x≤−9(Works in original inequality)
−9≤x≤0(Doesn't work in original inequality)
0≤x≤5(Doesn't work in original inequality)
x≥5(Works in original inequality)
Answer:
x≤−9 or x≥5 or x=0

168
So you take the 144 divide 12(the dozen) so we could find how much 1 cost, it was 12. You added 2 more books so we add(12x2)+(144). That equals to 168
Hope this helps!
The total to be paid is 909.5.
You must do 7% of 850 which is 59.5 and add it to 850 which is 909.5

Answer:
<u>$11.65</u>
Step-by-step explanation:
Since each birdhouse 2.6 feet of plywood, and you are making 8 birdhouses, you have to is they are then you multiply 2.6 by 8 and get 20.8 square feet of plywood in total. Because each square ft is $0.56, you do $0.56 by 20.8 square ft you then get 11.648, but you round it to 11.65.
