Step-by-step explanation:
ii have no clue what this is
By creating a common denominator, you can compare different numbers to the same ratio. For example:
Take 2/3 and 3/4
Now 3/4 is the same as 9/12
And 2/3 is the same as 8/12
Now that they have the same denominator, you can tell that 9/12 is clearly greater than 8/12, meaning 3/4 is greater than 2/3.
Answer:
-2 a b + 2 b + 6 a^2 + 9
Step-by-step explanation:
Simplify the following:
2 a^2 + a b + 2 b + 4 a^2 - 3 a b + 9
Grouping like terms, 2 a^2 + a b + 2 b + 4 a^2 - 3 a b + 9 = (a b - 3 a b) + 2 b + (2 a^2 + 4 a^2) + 9:
(a b - 3 a b) + 2 b + (2 a^2 + 4 a^2) + 9
a b + a b (-3) = -2 a b:
-2 a b + 2 b + (2 a^2 + 4 a^2) + 9
2 a^2 + 4 a^2 = 6 a^2:
Answer: -2 a b + 2 b + 6 a^2 + 9

Step-by-step explanation:
● A standard deck of cards has:
● 52 Cards in 13 values and 4 suits
● Suits are Spades, Clubs, Diamonds
and Hearts
● Each suit has 13 card values:
2-10, 3 “face cards” Jack, Queen, King (J, Q, K)
and and Ace (A)
Basic Card Probabilities
● If you draw a card at random, what is the
probability you get:
● A Spade? P(Spade)=13/52
● A Face card? P(Face Card)=12/52 (or simply 3/13)
● A Red Ace? P(Red Ace) = 2/52
