Solve for x round your answer to the nearest 10th

sin 55 =13/x

x=13/ sin 55

x= 13/0.8192

x= 15.8691

x can be approximated to 20

(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
