Answer:
13
Step-by-step explanation:
It is a square so the length of 1 side = 
= 13
35. is c : square root of 64 is 8 and the square root of 8 can be simplifed to 4 x 2, square root of 4 is 2
36 is d : Denominator of the fraction represents what it is being rooted by and the numerator is what the regular number is squared by.
The equation that would represent the new area N of the floor of the cage would be
N=w2+4w which would be a
(x-h)²+(y-k)²=r² is the equation of a circle with radius of r
so if x-h=4 and y-k=3 then
4²+3²=r²
16+9=r²
25=r²
sqrt both sides
5=r
radius is 5 units
75/3000=x/4000
times both sides by 1000
75/3=x/4
times both sides by 4
300/3=x
100=x
answer is 100 hours
