Answer:
Values of x are: x=0 or x=-3 or x=-12
Step-by-step explanation:
The equation given to solve using zero product property is 
Zero property rule states that if ab=0 then a=0 or b=0
Taking x common from the equation:

Applying zero product rule

Now, solving 
Using quadratic formula to find value of x

Putting values

So, Values of x are: x=0 or x=-3 or x=-12
Answer:
n=R
Step-by-step explanation:
f(n)=9n+1
187 ft/s. I think that this might be an equation, but if it is not, I'm sorry.
1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded
2) c, e, and f
