-26z - 15
Step-by-step explanation:
tp simplify an expression, you combine all the things with z in them and all the plain numbers. In this case you have a negative 20z and a negative 6 z, which makes negative 26z. The only number is -15 so there's nothing to combine with that. Put the pieces together and you have -26z-15
Factorize
(x- 8 )(x+ 4)

x-8=0 x=8
x+4=0 x=-4
Count the shaded squares and say there are 44 shaded that would be 44/100 or 11/25 as simplified and 0.44

All except for the third option are correct
