Use the distributive property of multiplication to evaluate 2(3 – 1). Show your work in your answer.

What is the area of the trapezoid shown ?

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

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.
