Which equation results from taking the square root of both sides of (x - 9)2 = 81?
O x-9 = +9
O x + 9 = +9
O x + 3 = +9
O x-3 = +9

x-9 = 9     x-9 = -9

Step-by-step explanation:

(x - 9)^2 = 81

Take the square root of both sides

sqrt((x - 9)^2) = ±sqrt(81)

x-9 = ±9

x-9 = 9     x-9 = -9

the equation results from taking the square root of both sides of (x - 9)2 = 81 is x-9 = 9     x-9 = -9

Step-by-step explanation:

You basically have to take the square root of both sides to get your final answer.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
