Answer:
1 real zero; 2 complex zeros
Step-by-step explanation:
A cubic will have 3 zeros. The number of positive and negative real zeros can be determined using Descartes' rule of signs.
There are no sign changes in the coefficients of the function as written, so there are no positive real roots. (+++)
If odd-degree terms have their sign changed, then there is one sign change. (-++) That indicates there is one negative real root.
The remaining two roots will be complex.

Mode= 24.
median = 40.
range= 62.
mean = 27.
Answer:
D. for the first one, A. for the second (not certain)
Step-by-step explanation:
1. 36/2 (two books every visit) = 18, multiplied by 3 because that's how many often he does to the library (every 3 weeks)
2. 13/2 = w/5 because for every 13 cups of water, there is two cups of cleaner, so for w (unknown amount of water) there would be 5 cups of concontrated cleaner.
