15h + 80 = 140
If you wanted to solve how many hours he worked:
15h + 80 = 140
15h = 60
h = 4.
15x12=180
180$ simple unless u have a different way to do it
We can't really factor it, because it's already simplified. We only need to add...


Have a nice day! :)
15%. 480-72=408
480x15%= 72
Answer:
2y² + 14y - 15
Step-by-step explanation:
(2y² + 8y - 9) - (- 6y + 6)
Remove first parenthesis and distribute second by - 1
= 2y² + 8y - 9 + 6y - 6 ← collect like terms
= 2y² + 14y - 15
