When it is 3: 10, what kind of angle is formed by the hands of the clock?

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible
