Answer:
By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.

Answer:
Step-by-step explanation:
PEMDAS
anything done in the parentheses comes first
so you have to add first then multiply
this is not the distributive property unless the two numbers in parentheses are not like terms
 
        
             
        
        
        
3. Answer: a) RT
                    b) XZ
                    c) TS
4. Answer: a) 26
                   b) 58
                   c) 21.5
                   d) 127
<u>Step-by-step explanation:</u>
2(PT) = AE              2(CP) = AN                 2(CT) = EN 
2(13) = AE               2(29) = AN                  2(CT) = 43
   26 = AE                  58  = AN                      CT  = 21.5
Perimeter = AE + AN + EN
                 = 26 + 58 + 43
                 = 127
 
        
             
        
        
        
293/12 is 24 and a lot of numbers. I think it is 24.4166667.
