Answer:
z=2
Step-by-step explanation:
I used cross multiplication to solve this.
2/9z=1/9
1(9z)=2(9)
9z=18
Answer= z=2
its because 9 has a z next to it so we have to multiply the z, and we now the they simplified the fraction so we have 1/9, and why did i ay its z=2? because 9xz which is 2 is 18. sorry if my explination is terrible.
basically you have to calculate the perimeter-
4+4+0.8+0.8=8+1.6=9.6
[2, 4]
i think it is 0.33 probably wrong
i am proably wrong
160%
1.6*150=240
