A painter takes 13 hours to paint 3 rooms. how long will it take the painter to paint 9 rooms

9 rooms / 3 rooms = 3

It will take him 3 times as long.

13 hours x 3 = 39 hours

39 hours

39 hours

Step-by-step explanation:

13h = 3 rooms

3 x 3 = 9

13 x 3 = 3 x 3

39h = 9 rooms

(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
