Answer:
144 miles
Step-by-step explanation:
The scale of map B is (3.4 cm)/(6.8 cm) = 1/2 that of map A. Then the distance (d) between the cities is ...
(1.8 cm)/d = (1/2)·(1 cm)/(40 mi)
Multiplying by d·80 mi, we get ...
144 mi·cm = d cm
Dividing by cm, we have ...
144 mi = d
The distance from Gladville to Columbus is 144 miles.
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
I believe the answer is 6
