It’s so cool I don’t understand
Explanation
Answer: 3 : 1
Step-by-step explanation:
We know that the ratio of A to B is given by :-
or A : B .
Given : Number of students having brown hair = 15
Number of students having black hair = 5
Then , the ratio of students with brown hair to students with black hair will be :-
Hence, the ratio of students with brown hair to students with black hair = 3 : 1.
There are two red suits of 13 cards ... 3 face cards in a suit and 2 red suits, so there are 6 red face cards. Thus, ... A five card hand is drawn from a standard deck of 52 cards.

Answer:
The answer is: 5(x+8)(-x+1)
Step-by-step explanation:
To factorize, you can take the FACTORS of 5x^2 and 8. Once you factor them, multiply them cross ways, like CROSS MULTIPLICATION. Moreover, if you do this and get -3x, then you have the factorization. For example
-5x^2 -3x + 8
5x 8
-x 1
Then cross multiply to get: -8x + 5x= -3x (this is correct)
Now you can find the factorization by just going across: (5x+8)(-x+1)
It is basically guess and check.
