If CD = 5x-8 and DB =3x+12 determine the length of CD

Don't know how to find x given these segment lengths

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
