Answer:
<u>One Rectangular Pan</u>
Step-by-step explanation:
Part C cannot be answered since the dimensions of the pool are not given.  Please check the question.
The cake pans may be compared by calculating the volume of each shape:
Rectangular pan:  Volume = Length x Width x Height
   Volume Rectangle = (13")*(9")*(2") = <u>234 in^3</u>
Round pan:  Volume = 
   Volume Round = (3.14)*(4")^2(2") = 100.5 in^3
Two round pans will hold 2*(100.5 in^3) or 201 in^3 of batter
One rectangular pan holds 234 in^3.
Go with the rectangular pan if you want more cake.
 
        
             
        
        
        
1. It is a triangular prism
        
             
        
        
        
its the first one 6k - 5
if u were to distribute u need to remember that 6 is negative so it changes -k to a positive 6k and then you would time 4 by -6 which would be -24 but u would just write it like 19 + 6k - 24. then u would add 19 to both sides by 19 which would be like adding 19 to -24 which would equal to -5 so it would equal to 6k - 5.
hope I explained the steps well enough for you.
