Factor because if we have
yz=0 then we can assume y and/or z=0
so factor
so the easiest way is to find what 2 numbers add to -6 and multiply to get 9 so
we know that they must be both - because we must have x+x=(-) and x^2=+ so therefor they must be negative
factors of 9=3 and 3 so
-3 and -3
-3+-3=-6 perfect
(z-3)(z-3)=0
set each to zero
z-3=0
add 3
z=3
z=3 is the answer

Answer:
24
Step-by-step explanation:
Using 9 as the figure number, Dion's equation tells us there are ...
2(9) +6 = 18 +6 = 24 blocks in figure 9
Answer:
the things wont load whats the question?
Step-by-step explanation:
The center of the circle that circumscribe about DABC is
.
A circle can be modelled after a expression of the form:
(1)
We can determine all coefficients by knowing three <em>distinct</em> points on plane.
If we know that
,
and
, then the solution of the system of linear equations is:
(2)
(3)
(4)

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:



The center of the circle that circumscribe about DABC is
.
