If ( y + 2)(5y -2)=0 and y> 0 what is the value of y

If there are 12 moths and some have 31 days and others have 30 days how many have 28 days?

What is the value of y? round to the nearest tenth

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
