Well it depends on how smart he is
In order to solve your question, you first have to understand what 1/3 of 36 is. you can do that by dividing 36/3.
when you do this you get the answer of 12. 1/3 of 36 is 12.
to get the 2/3 part. Add 12 to the existing part that you have.
Therefore, you have 24 plant eaters.
9 + n = x ?
i'm guessing since there's no answer to what the sum is
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3
