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
6 - 34 + 96 - 384 +...
a 1 = 6 , a 2 = a 1 * ( - 4 ) , a 3 = a 2 * ( - 4 ), a 4 = a 3 * ( - 4)...
a 5 = - 384 * ( - 4 ) = 1,536
a 6 = 1536 * ( - 4 ) = - 6,144
a 7 = - 6,144 * ( - 4 ) = 24,576
This is a sum of a geometric sequence:
S 7 = 6 - 24 + 96 - 384 + 1,536 - 6,144 + 24,576 = 19,662
Another way to solve this:
S 7 = a 1 * ( r^n - 1) / ( r - 1 ) = 6 * (( - 4) ^7 - 1 )/ (- 4 - 1)=
= 6 * (-16,385) / (-5 ) = 19,662

D is correct. Hope this helped.
She needs 27 crates to make 7 steps. It makes more sense if you draw it out for yourself.
