Answer:
3rd option
Step-by-step explanation:
Given z is inversely proportional to (y - 2)² then the equation relating them is
z = 
← k is the constant of proportion
To find k use the condition when y = 5, z = 9 , then
9 = 
= 
= 
( multiply both sides by 9 )
81 = k
z = 
← equation of proportion
A square has four sides, so divide 26 by 4, which is 6.5. Since they are asking for how many whole squares, Martin can make 6 squares out of the 26 sticks.
