The population of Candyworld is 14.4 Candys per acre. Exactly 792 Candys live in
Candyworld. How many acres is Candyworld? Only enter a numerical value in the answer
blank.

55

Step-by-step explanation:

D=m/v

D=14.4

M=792

V= unknown

14.4=792/v- multiply both sides by V

V • 14.4=792-divide both sides by 14.4

V=55

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
