Answer:
Each will receive  of the cake.
 of the cake. 
Step-by-step explanation:
Let the amount of cake = c 
Lisa, Juan and Isaac are the persons who are sharing half of a cake equally.
Number of persons = 3
Part of the cake shared = 
Fraction of the cake shared by each = 
                                                              =  
 
                                                              = 
Therefore, fraction of total cake shared by each member will be  of the total amount of cake.
 of the total amount of cake.
 
        
             
        
        
        
This is gonna be the answer. It’s 4+sqrt(19) and 4-sqrt(19). Which is approximately 8.36 and -0.36. In x intercept form, it’s (8.36,0) and (-0.36,0) also I solved this by completing the square. I hope this helps!!! Mark as brainliest!!!
