Answer:
it is 86
Step-by-step explanation:
House 1 has 6 sticks. House 2 has 11, house 3 has 16, and the pattern goes on. Each following house uses 5 more sticks. At design 17, we can use this pattern to solve for it. We would do 5*17, remembering to add 1 as house 1 has its own additional stick. 5*17 + 1 = 86

By the Pythagoras theorem:-
h^2  = x^2 + x^2   
    (where h = hypotenuse)
h^2 = 2x^2
h = sqrt2 x
        
             
        
        
        
Answer:

Step-by-step explanation:
- t  = time (in hours) → this is the independent variable
- s = total area cleaned (in square feet) → this is the dependent variable (as the number of square feet cleaned depends on the number of hours worked)
Therefore, if the rate of cleaning is 8 1/4 square feet per hour, the relationship between s and t is:

W=3L
W+W+L+L=72
Replace W with 3L: 3L+3L+L+L=72
8L=72
L=9
W=27
