Which of the following functions are quadratic functions? (select all that apply.) a. f(x) = 2x − 4 b. f(x) = 3 − x2 c. f(x) = 3x2 − x − 6 d. f(x) = 3 x2

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
