Answer:
It is irrational
Step-by-step explanation:
Hope that helps!
(x^2)/a^2+(y^2)/b^2=1
a>b
a=6, a^2=36
foci=(a^2-b^2)^(1/2)
4=(36-b^2)^(1/2)
16=36-b^2
b^2=36-16
b^2=20
b=2(5)^(1/2) or (20)^(1/2)
1=(x^2/36)+(y^2/20)
1. C
2.A
3.D
4. B These are the only math problems I can actually do because they're more like puzzles than anything.
6h + 5h - 3j = 11h - 3j (all u can do is combine like terms...if they're not like terms, they cannot be combined)
