Answer:
(x - y)(x + y)(x² + y²)
Step-by-step explanation:
- 
← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
-
= (x²)² - (y²)²
= (x² - y²)(x² + y²) ← x² - y² is also a difference of squares, then
= (x - y)(x + y)(x² + y²)
Answer: <em>(x+1)(x−4). </em>
Explanation: <em>x2−3x−4 x2−4x+x−4 x(x−4)+1(x−4) (x+1)(x−4). </em>
Answer:
Explanation:
Slope-intercept form formula:
For this formula we need the slope to find the slope use the slope formula:
Plug in the two points (1,-3) and (3,1)
=2
the slope is 2
Now use the slope-interpect formula and plug in the slope (m)
plug in one point I'll use (3,1)
1 = 6 +b
1-6=6-6+b
-5 = b
The equation would be:
Answer: p = 1/25
Step-by-step explanation:
Ok, you know that the probability of rolling a six is p = 1/5
now, if you want to have two sixes, then you have two events with a probability of 1/5.
And as you know the joint probability for two events is equal to the product of the probabilities, then the probability of rolling two sixes is:
p = (1/5)*(1/5) = 1/25.
