Nonamiya [84]

Answer:

black = 0.28

white = 0.22

pink = 0.24

blue = 0.26

Step-by-step explanation:

Jason and his friend spun the spinner 100 times total. So for each time landed on a color, it can be counted as one percentage (for example, black had a 28% frequency). To transfer percentages to decimal form, simply bring the decimal point over by two spaces (28 becomes 0.28, something like 4 would become 0.04). Hope this helps! Feel free to ask any questions!

Help me to solve thisssss​
m_a_m_a [10]

Answer:

(a + 3)

Step-by-step explanation:

a³ - 9a = a(a² - 9) = a(a + 3)(a - 3)

a² + a - 6 = (a - 2)(a + 3)

a⁴ + 27a = a(a³ + 27) = a(a - 3)(a² + 6a + 9) = a(a - 3)(a + 3)(a + 3)

HCF = (a + 3)

Hope it helps.
