Answer
 7.21
Step-by-step explanation:
Data :
 (-3,-4) , (1,2)
Where 
 x₁ = -3 , x₂ = 1
 y₁ = -4 , y₂ = 2
Formula for distance
 D = √{(x₂-x₁)² + (y₂-y₁)²}
 = √{(l--3)² + (2--4)²} = √(16+36) =√52 =7.21

To solve for x you do these steps
x=number
1. do this following multiplication problem to get 0.9%
36/x*100%= 0.9%
2. now do the opposite of what you did before to get x
36 divided by 0.9%= x
36 divided by 0.9%= 40
x = 40
