2(x2 + 6x) = –3

2(x2 + 6x) = 3

x + 3 = Plus or minus StartRoot StartFraction 21 Over 2 EndFraction EndRoot

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
