(x+2)(x+6)=0
2 answers:
Answer: The correct option is
(C) Zero product property.
Step-by-step explanation: The given problem is
To conclude that x+2=0 or x+6=0, one must use which of the given properties.
We know that
for any two expressions E and F, we have
This property is known as Zero product property.
Therefore, to conclude x+2=0 or x+6=0 from the given problem (i), we must use the Zero product property.
Thus, (C) is the correct option.

Answer:
Step-by-step explanation:
Birth Rate in 1994 = 14.6 births per thousand population.
Birth Rate in 2004 = 14.32 births per thousand population.
A linear equation is of the form: y=mx+c
Where:
- x=years after 1994
- y=the birth rate
- m=Yearly Birth Rate
First, we determine the birth rate per year
Therefore, a linear equation that relates y in terms of x is of the form:
When x=0, y=14.6
14.6=-0.028(0)+c
c=14.6
Therefore, the linear equation that relates y in terms of x is:
