Hello :
This number is : x
you have : x + 2x² = 6
2x² + x -6 = 0
Δ = b² -4ac a = 2 , b = 1 , c = 6
Δ = 1² - 4(2)(6) = 49 = 7²
X1 = (- 1 +7)/4 = 3/2
X2 = (-1-7)/4 = -2
Answer:AC = 20
BK = 9.6
Step-by-step explanation:
AC is found using the Pythagorean theorem in the usual way:
AC² = AB² + BC²
AC² = 12² + 16² = 144 +256 = 400
AC = √400
AC = 20
You may recognize this is a 3-4-5 triangle scaled by a factor of 4.
__
Then BK is found using similar triangles. All of the triangles in the figure are similar*, so ...
long side / hypotenuse = BC/AC = BK/AB
BK = AB(BC/AC) = 12(16/20) = 12×0.8
BK = 9.6
