Answer:
The inequality is equivalent to x(x+2)(x−3)>0 , with the additional conditions that x≠0 and x≠3 .
Since x(x+2)(x−3) only changes signs when crossing −2 , 0 and 3 , from the fact that the evaluating the polynomial at 4 yields 24 , we see that the polynomial is
positive over (3,∞)
negative over (0,3)
positive over (−2,0)
negative over (−∞,−2)
Thus the solution set for your inequality is (−2,0)∪(3,∞) .

Answer:
C = 20
Step-by-step explanation:
The sum of the angles of a triangle is 180
73+87+c =180
Combine like terms
160 +c = 180
subtract 160 from each side
160+c-160 = 180-160
C = 20
Answer:
11.57
Step-by-step explanation:
We have a simple formula to solve this:
where
SS is sum of squares
s^2 is the variance, and
n is the number of data points
We are given all the info to find out s^2. Hence,
0.91 = 91/100 = 91%
That's basically it
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Subtract 4 from each side
4-4 - 2(x - 3) = 24-4
-2(x-3) = 20
Divide each side by -2
-2(x-3)/-2 = 20/-2
x-3 = -10
Add 3 to each side
x-3+3 = -10+3
x = -7
