Answer 1

Answer:

Choice B. only Shota

Step-by-step explanation:

16z^2 - 40z

the greatest common value is 8z

8z (2z^2 -5)

24z^2 - 40z

the greatest common value is 8z

8z (3z^2 -5)

$\frac{8z (2z^2 -5)}{8z (3z^2 -5)}$

8z / 8z = 1

= $\frac{8z}{8z}$ x $\frac{2z^2 -5}{3z^2 -5}$ = 1 x $\frac{2z^2 -5}{3z^2 -5}$ = $\frac{2z^2 -5}{3z^2 -5}$ (Shota)
