Why are my points going up? I'm not even answering anything.

Cherie measures and records the lengths and sizes of the same style of a sandal found at a shoe store. which equation can be used to determine the approximate shoe size, s, for a foot length of x inches? s = x – 2 s = 2x – 10 s = x + 6 s = 2x + 4

It says factor each expression completely 8y+48

We just started the introduction into circles and i have no idea how to do this.
