The supplement of a 42° angle is

Step-by-step explanation:

If an angle is 42 degrees less than its supplement, find each angle. Two angles are supplements if their measures add to 180 degrees. The second angle is 42 less than x.

(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
