Answer:

BD = 13

Step-by-step explanation:

AC is an angle bisector and divides the opposite into segments that are proportional to the other 2 sides, that is

\frac{AB}{AD}  = \frac{BC}{DC} , substitute values

\frac{12}{27} = \frac{x}{x+5} ( cross- multiply )

27x = 12(x + 5)

27x = 12x + 60 ( subtract 12x from both sides )

15x = 60 ( divide both sides by 15 )

x = 4

Thus

BD = x + x + 5 = 2x + 5 = 2(4) + 5 = 8 + 5 = 13

Use the given root to find the remaining root of the function. Root: x = - 3 Function: f(x) = x ^ 2 + x - 6
ra1l [238]

Answer:

x = 2

Step-by-step explanation:

Since we know one root is -3, we know one factor of the equation is (x+3)

From there we can use the factor we know to factor the rest of the equation:

x^2 + x - 6 = (x+3) * ?

Since know -6 is just 3 * -2 and since 3-2 is 1,

(x+3)(x-2) = x^2 + x - 6

From there,

x - 2 = 0

x = 2
