Answer: it's 31.5
Step-by-step explanation:because you would times 9 by 21 then divide by 6
9*21=189
189/6=31.5

Answer:
Rectangle: 112m
Trapezoid: 28m
Step-by-step explanation:
The area of the rectangle is 8*14, which is 112. The area of the trapezoid is ((base1 + base2)* height)/2. That is ((4+10)*4)/2, which is 28.
 
        
                    
             
        
        
        
This is an arithmetic sequence because there is a common difference between terms, a constant found when subtracting the preceding term from any term in the sequence.  In this case the common difference is 7.
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial value, d=common difference, n=term number
Here we have a=44 and d=7 so
a(n)=44+7(n-1)
a(n)=44+7n-7
a(n)=7n+37, so the 39th term is:
a(37)=7(37)+7
a(37)=266
I am assuming that 44 is the first term, not the 5th term...if 44 was the fifth term let me know and I will edit to reflect that...
