69
Step-by-step explanation:
k = 13 is the value of k in quartic equation.
What does the term "quartic equation" mean?
An equation of the fourth degree, often known as a quartic equation, is one that reduces a quartic polynomial to zero. in which a 0. A quartic function's derivative is a cubic function.
Let α = 7x
β = 6x
α + β = 7x + 6x = k/3 ............1
13x = k/3
αβ = 7x × 6x = 14/3
42x² = 14/3
x² = 14/3 × 42
x² = 1/9
x = 1/3
now putting value of x in 1
7/3 + 6/3 = k/3
1/3( 7 + 6 )= k/3
k = 13

Answer:
Correct choice is C. Similar AA.
Step-by-step explanation:
We have been given a picutre of the triangles. Using those information we need to find the correct choice.
Consider triangle FGH and triangle JKL.
∠F≅∠J {Both are equal to 30°}
∠H≅∠L {Both are equal to 50°}
Then triangle FGH is similar to the triangle JKL by AA - similarity of the triangle. Because we are getting two congruent angle pairs.
Hence correct choice is C. Similar AA.
