C. combine like terms 7 + 3 -1 9b then 11-4
The common factors of 24 and 48 are 1, 2, 3, 4, 6, 8, 12, and 24.
Factors are the numbers that can be multiplied with another number, to equal the product stated. Common factors are the factors that both stated products have.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, and 24.
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Finding all the shared factors, will give you a final answer of 1, 2, 3, 4, 6, 8, 12, and 24.
I hope this helps!
Q1. The answer is <span>(x – 14)(x + 14)
</span>
x² - 196 = x² - 14²
a² - b² = (a - b)(a + b)
a = x, b = 14
x² - 196 = x² - 14² = (x - 14)(x + 14)
Q2. The answer is (3x - 8)(3x + 8)
9x² - 64 = (3x)² - 8²
a² - b² = (a - b)(a + b)
a = 3x, b = 8
9x² - 64 = (3x)² - 8² = (3x - 8)(3x + 8)
Q3. The answer is (7x - 4)²
49x² - 56x + 16 = (7x)² - 2 * 7x * 4 + 4²
(a - b)² = a² - 2ab + b²
a = 7x, b = 4
49x² - 56x + 16 = (7x)² - 2 * 7x * 4 + 4² = (7x - 4)²
Let's just go through all possible answers and see which ones give what you are asking for.
1
the Total number of marbles is 10
You have 2 blue marbles
P(blue) = 2/10 = 1/5 which is not a good answer.
2
There are 3 red marbles.
P(red) = 3/10 = 0.3 which is greater than 1/5 <<<< Possible answer.
3
3 red marbles out of 10 = 3/10
2 blue marbles = 2/9
Probability of (red then blue)= 3/10 * 2/9 = 1/15 which is not greater than 1/5
4
1 white marble replacing it and white again.
1/2 * 1/2 = 1/4 which is greater than 1/5 <<<<<<<< Answer
5
There are 5 white marbles. 5/10 is the probability of drawing a white. P(white) = 1/2. That is greater than 1/5.<<<< Possible Answer
