It seems like you're referring to a specific curriculum or course material for a Math class. However, I don't have access to specific courses, their contents, or documents like "Math7B.U2L8.SemesterASkillsReview.Spring25."
If you could provide more context or detail about the specific math concepts or problems you're dealing with in this unit or skills review, I'd be happy to help you go over those topics, explain concepts, or solve problems!
