Answer:

\frac{2}{(x + 3)}

Step-by-step explanation:

\frac{2x - 10}{x^{2} - 2x - 15}

pull 2 from top

\frac{2(x - 5)}{x^{2} - 2x - 15}

we are looking to cancel (x-5) so will start with

(x - 5)(x + 3), selected (x+3) because the sign must be negative and must multiply to -15

\frac{2(x - 5)}{(x - 5)(x + 3)}  

now cancel (x-5)

\frac{2}{(x + 3)}

Westkost [7]
A basketball is the shape of a sphere.

The volume of a sphere is given by

V= \frac{4}{3} \pi r^3

Given that the diameter of the basketball is 10 in., thus the radius is 10 / 2 = 5 in.

Thus, the volume of the basketball is given by

V= \frac{4}{3} \pi(5)^3 \\  \\ = \frac{4\times125}{3} \pi=523.6\ in^3

Therefore, The best approximate of the volume of the basketball is 5\times10^2\ in^3
