Given a temperature C in celsius, you can convert it to Fahrenheit by using the formula

In your case C=39, so you have

Answer:
Step-by-step explanation:
consider 6x^2-8x +k
disc .=(-8)^2-4*6*k=64-24k
it has no solution if 64-2k<0
or 64<2k
or 2k>64
k>32
it has two zeros if 64-2k≥0
or 64≥ 2k
or 2k≤64
or k≤ 32
it has one zero if Disc. =0
64-2k=0
2k=64
k=32
