Find a common denominator first 
2 24/40 - 1 15/40 = 1 9/40 
it is already in simplest form so you can not reduce it
        
             
        
        
        
Answer:
nth term--n+3
Step-by-step explanation:
numbers increase by add three each time
 
        
             
        
        
        
As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.
        
             
        
        
        
Answer:
See sample table below.
Step-by-step explanation:
The function is given as :
f(x) = 3ˣ
A table of values can be formed as ;
x                <u>calculations</u>           f(x)
-4               3⁻⁴                          0.0123
-3               3⁻³                          0.0370
-2               3⁻²                          0.1111
-1                3⁻¹                           0.3333
0                 3⁰                            1.000
1                  3¹                             3.000
2                 3²                             9.000
3                 3³                              27.00
