What is a mixed number betweeen 3 3/11 and 3 2/5

3 4/11.

Step-by-step explanation:

3/11 = 15/55

2/5 = 22/55

So a number in between  could be 20/55

= 4/11.

So the mixed number could be 3 4/11.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
