You round up if the number is bigger then 5 and the number stays the same if it's smaller then 5
B) 0.45 and D) 9/20 are both eqivalent to 45%.
(5p² - 3) - (2p² - 3p³)
(5p² - 2p²) - 3 + 9p³
3p² - 3 + 9p³
5.0 should be the answer if I’m not mistaken but it should be right
Slope = change in y / change in x
= (15 - 9) / (7 - 5)
= 6 / 2
= 3
