Answer:
12x² +3x = 96
Step-by-step explanation:
x = 4(x + 3)( 3x - 8)
x = (4x + 12) (3x - 8)
x = 4x(3x - 8) + 12(3x - 8)
x = 12x² - 32x + 36x - 96
x = 12x² + (-32x + 36x) - 96
x = 12x² + 4x - 96
0 = 12x² + 4x -x - 96
0 = 12x² + 3x -96
96 = 12x² + 3x same as 12x² +3x = 96
21,000 rounded to the nearest thousand will be 20,000
Answer: 
Step-by-step explanation:
Given: Number of cards in a standard deck = 52
If we already chosen a diamond card, then the number of cards left in the deck =52-1=51
The number of spades remains same = 13
Now, the probability that you choose a spade, given that you have already chosen a diamond is given by :-

Hence, the the probability that you choose a spade, given that you have already chosen a diamond 
Answer:
No
Step-by-step explanation:
Since 1/2 =0.5
0.5 > 0.4
Therefore
1/2 >0.4
