3 Haley's recipe calls for 5.5 cups of an ingredient. Her measuring bowl only has measurements marked in liters, Which measurement is closes to the number of liters of the ingredient that Haley needs for her recipe?
A 0.04 liters
B 1.3 liters
C 2.3 liters
D 0.2 liters

The answer would be B

Step-by-step explanation:

You can search up how to figure out how many cups are in a liter or the other way around but thats what i got.

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
