Which of the following is an odd function?
f(x)= 3x^2+x
f(x)=4x^3+7
f(x)=5x^2+9
f(x)=6x^3+2x

F(x)=6x^3+2x

Step-by-step explanation:

Odd functions have solely odd powers of x.  

F(x)=4x^3+7      is actually   F(x) = 4x^3 + 7x^0, which is neither even nor odd.

F(x)=6x^3+2x   has only odd powers of x:  x^3 and x^1.  This is the answer.

Step-by-step explanation:

======================================================

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
