Polynomial with real coefficients always has even number of complex roots. We know that one of them is 2 + 5i so the second one will be 2 - 5i and:
Answer B.
Just substitute each number into the expression:
5(5) - 6(3) + 20(1/4)/4(3)(1/4) = 25 - 18 + 5/3 = 7 + 5/3 = 26/3 or 8 and 2/3.
Answer:
50km = 0.33cm
280km = 1.87cm
142.5km = 0.95cm
Step-by-step explanation:
Ratio is 0.5/75 = 1/150 cm per km
