Answer:

x = √12

Step-by-step explanation:

Easy:

3x^2 = 36

Cancel out the 3 so it is only x^2; you can do this by dividing each side by 3 which gives you:

x^2 = 12

Square root the entire thing to get rid of the square and you get the answer

Hannah is participating in a marathon. She can run 4 miles in 50 minutes. At this rate, how long will it take Hannah to run 30 m

ra1l [238]

The answer is c

Because if it takes 50 minutes to run 4 miles you need to divide 50/4 and you will get 12.5 and then multiply that by 30 cause she is trying to run 30 miles and that will get you 375 and then divide that by 60 cause their are 60 minutes in a hour and you will get 6.25
