a parallelogram has diagonals 34kin and 20in and one side measures 15in. find the length of the other side
5z(z-8)(z+5)=0
solving an equation in factored form
(5-y)(4y+3)=0
(z+9) (z-8)=0
if avarage of a,b,c,d is 5 and a<b<c<d what is the greatest possible value of d if all of them are positive integer?
2x²+7x-3
z+9, z-8
