Solve the quadratic equation for x what is one of its roots 3x2-14x-5=0

x = -1/3     x=5

Step-by-step explanation:

3x^2-14x-5=0

(3x+1) (x-5)=0

Using the zero product property

3x+1 =0   (x-5)=0

3x=-1        x=5

x = -1/3     x=5

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

my answer is$ 12

step-by-step explanation:

because 15 -2=12
