Use combining like terms to write an equivalent expression for -9n - 6 + 3n + 10​

-6n+4 ; 22

Step-by-step explanation:

1. -9n + 3n = -6n

2. -6n-6+10

3. -6 + 10 = 4

4. -6n + 4

5. -6*-3 = 18

6. 18+4 = 22

answer to first part: -6n + 4

answer to second part: 22

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

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
