It takes 45 minutes for 4 people to paint 5 walls. How many minutes does it take 6 people to paint 4 walls?

1 answer:

3 0

45/5 = 9minutes/wall = 1wall/9minute/4 people = (1/36) per minute per person

(1/36)*6 = 1/6 wall per minute per 6 people * 24 = 4 walls in 24 minutes

24 Minutes total

Dan factored x^2+121 into (x+1-11)

babunello [35]

Answer:

Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).

Step-by-step explanation:

The difference of two squares is a special form. a² - b² = (a+b)(a-b).

But, the sum of two squares is prime. a²+ b² cannot be factored.
