87.96 You need the height of the circle which is
14 because 7 is only the radius. And you put it into the equation and solve C=2πr
The general form of a quadratic equation is that which is expressed in a form,
ax² + bx + c = 0
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.
It is 236.39. Explanation if Margo is driving 61.4 miles per hour he will go that many miles an hour, tip (don't think of it as speed in math). If 3.85 hours pass multiply that against 61.4 miles an hour. Getting you 236.39. Here is an explanation. His amount of distance he covers per hour is 61.4 so every hour that number adds up and to get this just multiply against 3.85 hours. Do you get it now?
