Assume 2 kg of apples is 1 dozen and that each apple has 8 seeds. how many apple seeds are in 14 kg of apples?

There are 672 seeds in 14 kg of apples

Step-by-step explanation:

2 kg of apples = 1 dozen

1 dozen = 12 apples

So, 2 kg of apples =12 apples

1 kg of apples =

1 kg of apples =

14 kg of apples =

Each apples has 8 seeds

So, 84 apples has seeds =

Hence there are 672 seeds in 14 kg of apples

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
