Shau-uen solved the equation 18.5 w + 6.5 w minus 2.8 w = 149.1. Her work is shown below. Step 1 18.5 w + 6.5 w minus 2.8 w = 149.10 Step 2 25 w minus 2.8 w = 149.1 Step 3 Negative 2.8 w = 5.964 Step 4 w = negative 2.13 In which step did Shau-uen make her first error?

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
