You are preparing for a breaktast party and need enough milk for 20 people. Each person will drink about 200 mL of milk
Which is the best estimate of the amount of milk you
should
prepare: 400 mL or 4 L? Why?
 please help me i have this due super soon

4 L

Step-by-step explanation:

20 × 200 = 4000 mL in total, or 4 L

So, the best estimate is 4 L.

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
