Answer:
The correct option is 1.
Step-by-step explanation:
If a quadratic equation is defined as
.... (1)
Then the sum of the roots is -b/a and the product of roots is c/a.
The given equation is
... (2)
From (1) and (2) we get a=3, b=11 and c=-4.
The sum of roots is

The sum of roots is
.
Therefore the correct option is 1.
Answer: 10
Explanation:
formula for hypotenuse : a^2+b^2=c^2
8^2+6^2=c^2
64+36=c^2
100=c^2
so we find the square root of 100 and its is:
c=10
