Answer: f(-6) = -\frac{12}{11}, f(-4) = \frac{4}{3}, f(6) = \frac{12}{11}

<u>Step-by-step explanation:</u>

#1 - 7 and 9 are correct but 8 is wrong:

f(x) = \frac{2x}{x^{2}-25}

f(-6) = \frac{2(-6)}{(-6)^{2}-25}

      = \frac{-12}{36-25}

      = \frac{-12}{11}

f(-4) = \frac{2(-4)}{(-4)^{2}-25}

      = \frac{-8}{16-25}

      = \frac{-12}{-9}

      = \frac{4}{3}

f(6) = \frac{2(6)}{(6)^{2}-25}

      = \frac{12}{36-25}

      = \frac{12}{11}

Answer:

Similar triangles states the length of the  corresponding sides are in proportion.

In a given similar triangles:

Labelled the diagram:

Triangle BAC and triangle DAC are similar.

then;

Corresponding sides:

\frac{AB}{AD} = \frac{BC}{DC}

AB = x units , BC = 5 units, AD = 15 units and DC = BD-BC = 8-5 = 3 units

\frac{x}{15} = \frac{5}{3}

By cross multiply we get;

3x = 15 \cdot 5

Simplify:

3x = 75

Divide both sides by 3 we get;

\frac{3x}{3}=\frac{75}{3}

Simplify:

x = 25 units

Therefore, the value of x is 25 units.
