Natalie is thinking of repaying all amounts outstanding to her grandmother. recall that cookie creations borrowed $2,000 on november 16, 2017, from natalie’s grandmother. interest on the note is 9% per year, and the note plus interest was to be repaid in 24 months. recall that a monthly adjusting journal entry was prepared for the months of november 2017 (1/2 month), december 2017, and january 2018.

i can you with this sweetie!

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
