Evaluate the factorial expression. (8 - 5)!

I’m not sure how to do it when there are parenthesis involved.

Two fire-lookout stations are 190 miles apart, with station a directly south of station b. both stations spot a fire. the bearing of the fire from station a is upper n 55 degrees upper e and the bearing of the fire from station b is upper s 60 degrees e. how far, to the nearest tenth of a mile, is the fire from each lookout station?

Asegment in the complex plane has a midpoint at 7 – 2i. if the segment has an endpoint at 11 – 3i, what is the other endpoint?

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
