The cobra there's helly pad is 2/5 of a mile from the control center the food will be dropped when it's 2/3 of the way there how far is its drop point from the center control die what is 2/3×2/5

4/15 miles.

Step-by-step explanation:

2/3 * 2/5

= 2*2 / 3*5

= 4/15

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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
