Ln(x) should be the answer
Answer:
x = 3 or -3
Step-by-step explanation:
So you have the equation x² - 9 = 0
Move the 9 to the other side: x² = 9
Then take the square root of both sides: 
= ±
x = ± = ±3
x = 3 or -3
Well first you need to change minutes to hours (240 min=4 hours, 240/60 min). Then you would just multiply 70 km by 4 hours to get 280 km.
There can be 6 teams because 2 is the lowest number that can go into both 12 and 18. (12/2) = 6...and I know (18/2 = 9) but there wouldn't be enough boys to make 9 teams
there will be 6 teams each containing (12/6) = 2 boys and (18/6) = 3 girls
12 x 86=1032. There are 1,032 parking spaces in the garage
