Using the discriminant from the quadratic formula (√b²-4ac) since that is the only way to get a solution to not be real (b²-4ac has to be negative), we get
m²-4*3*7=m²-84. Solving for m if m²-84=0, m²=84 and m=+-√84. Therefore, if m is positive, the highest possible value of m is √84. However, we have to find the integer value - with a bit of guess and check, we find that 9²=81 and is the integer you get by rounding down √84 (if we rounded up, 10 would have real solutions since we need the square to be less than 84 to get m²-84 negative). Therefore, 9 is our answer
Answer: The first one does not belong, neither does the third.
Step-by-step explanation:
The second one belongs as 30+5=35. You can divide 35 by 5 to get A=7. This is a valid answer. The third is the same as the first. The fourth acts for 30+25=5. 55/5=11.A=11. This is also a valid answer. So, the first one does not belong and neither does the third.

Answer:
C
Step-by-step explanation:
Florida is on the 30 mark so its 30 then Alaska is in between 10 and 20 half so half of these numbers is 15 then your going to subtract 30-15 leaving you with 15 and as you can see that answer is presented
