Ir x+2 has a value of 5. then which of the following is the value of x(x+2)+3(x+2)? Show the work that leads to your answer.
(1) 30
(3) 15
(2) 25
(4) 10

we are using binomials

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.
