How to solve this ?
18m + 5n = - 11
12m + 11n = 31

Which term best describes the association between variables a and b

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
