Use the following figures to find out if an error exists either in the bank's balance or the customer's record book. the ending balance on the statement is $378.19. three checks are outstanding: #5104 for $30.90; #5123 for $17.50; and #5124 for $98.10. a deposit of $309.00 has not yet been credited. a service charge of $4.21 has been made. the balance in the record book is $544.90. does an error exist? yes or no?

                                        = $231.69

Deposit is added in the balance = 231.69+309

                                                     = $540.69

Service charge is been deducted = 540.69 -4.21

Balance in the bank statement = $536.48

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
