Find the nonpermissible replacement for y in this expression y+3/y-1

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b. you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c. you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d. you spend $5 plus $10 per week until you have less than $45.

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0
