Using this model, the predicted number of owls in year 9 is about -
23. Does this prediction make sense? Why or why not?
O A. Yes, because the owl population is endangered.
O B. No, because the owls went to live somewhere else.
C. No, because you can't have a negative number of owls.
O D. Yes, because that is the result of substituting x = 9.

Step-by-step explanation:

Each side of the square is s meters long.

By the Pythagorean Theorem,

length of diagonal = √(s²+s²)  = √(2s²) = s√2 meters

s√2 =  11.3

s = 11.3/√2

perimeter = 4s = 45.2/√2 ≅ 31.96 meters
