2y^2-10x^2=40
16y^2-4x^2=64
i do not understand how to solve these problems or write them in standard form
---------------------
All 6 are hyperbolas.
Standard form is

x^2/16-y^2/4=1
This is standard form
a = 4, b = 2, c = 1
---------------------
x^2/9-y^2/36=1
This is standard form
--------------
y^2/25-x^2/4=1
This is standard form
--------------
x^2-4y^2=4
Divide by 4

------------------
2y^2-10x^2=40
Divide by 40

a = 2, b = sqrt(20), c = 1
--------------------
16y^2-4x^2=64
