Answer:c
Step-by-step explanation:
Because the x’s repeat
x^2 +7x +10
when factored becomes
(x+2) (x+5)
the zeros are x +2 = 0, x = -2
x +5 = 0 x = -5
zeros are -2 and -5
X^2+3x+3+[(2x^2+13+15)/(x+5)] is equivalent to option 4. im sorry if i got my math wrong but i hope this helps.
For a set of trials

. In this case our desired out come is all multiples of 3: 3,6,9 and 12. The total number of outcomes can be found as 100 by adding up all the frequencies. Thus our experimental probability is

.
