Answer:
-3(3z+91)
Step-by-step explanation:
Hope this helps :)
−12(7z+4)+15(5z−15)
= -3(4(7z+4)-5(5z-15)
= -3(28z+16-25z+75)
= -3(3z+91)

We are given the following sequence:

The formula that we can use to obtain the sequence is the following:

Because when we replace the given terms we get:

For the next term:
Answer:
see below
Step-by-step explanation:
A discriminant value of zero means there is exactly one x-intercept. The graph below has that characteristic.
_____
<em>Comment on discriminant</em>
discriminant > 0, two (2) x-intercepts (first 2 graphs)
discriminant < 0, no (0) x-intercepts (third graph)
