The length of a new rectangular playing field is 7 yards longer than triple the width. If the perimeter of the rectangular playing field is 334 yards, what are its dimensions?

It says factor each expression completely 8y+48

Icould really use some with this question.

Logan wants to know how many skateboards have defective parts. he inspects 20,000 skateboards and keeps track of the number of defects per board. use his probability distribution table to find the expected value for defects on a skateboard.
