PLEASE HELP ME.

Answer 1

Hey deepali,

let the age of the zebra be x.
therefore according to question before 5 years her age will be x-5 years.
therefore
(x-5)2=11+5x
​x2+25-10x=11+5x
​x2-10x-5x+25-11=0
x2-15x+14=0
so when we multiply 14 and 1 we get 14 and when we add them we get 15,therefore
x2-14x-x+14=0
x(x-14)-1(x-14)=0
(x-14)(x-1)=0
so x can be either 1 or 14
but if age is 1 the age before 5 years is -4 .

so age of zebra is 14 years

hope this is helpful to you thank you.​
