Theo started to solve the quadratic equation (x + 2)2 – 9 = –5. he added 9 to both sides and the resulting equation was (x + 2)2 = 4. next, he took the square root of each side. which was the resulting equation of that step? x + 2 = ±4 x + 2 = ±2 x + 2 = ±8 x + 2 = ±16

x+2=±2

Step-by-step explanation:

Here the original equation was:

Then Theo added 9 to both the sides to get,

After this he took square root of each side,

So this simplifies to

x+2=±2

 option B

(B)  x + 2 = ±2

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
