Answer:
n=0
Step-by-step explanation:
3n+4+14n=4-32n
3n+14n=-32n
17n=-32
17n+32n=0
49n=0
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12
hope this helps !

Answer: They run the same distance</h3>
Explanation:
The fraction 5/2 turns into 10/4 when you multiply top and bottom by 2
5*2 = 10
2*2 = 4
Or you could use long division or a calculator to notice that
5/2 = 2.5
10/4 = 2.5
Both result in the same exact decimal value, so the fractions must be equal. Each person runs exactly 2.5 miles everyday.
