A garden store recently sold 12 squash seed packets and 27 other seed packets. Considering this data, how many of the next 78 seed packets sold should you expect to be squash seed packets?

12 + 27 = 39 total seed packets initially sold.

12 / 39 × 100 = 30.8%. 30.8% of seed packets sold are squash seed packets.

30.8% of 78 = 25 squash seed packets sold.

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
