Answer:
(x + 1)(x - 1)(x² + 9)
Step-by-step explanation:
Factorise the following:
x⁴ + 8x² - 9
The factors of -9 that sum to 8 are 9 and -1.
So,
x²(x² + 9) - 1(x² + 9)
(x² - 1)(x² + 9)
x² - 1 = x² - 1²:
(x² - 1²)(x² + 9)
Factor the difference of two squares.
x² - 1² = (x + 1)(x - 1):
(x + 1)(x - 1)(x² + 9)
If you factor 3y from each of these, you should get (8x^2) and (5y). These are completely simplified.
Your greatest common factor is 3y
Step-by-step explanation:
Let the points of the given coordinates ( -3 , -1 ) & ( 0 , 3 ) be A and B respectively.
- A ( -3 , -1 ) & B ( 0 , 3 )
Let A ( -3 , -1 ) be ( x₁ , y₁ ) & B ( 0 , 3 ) be ( x₂ , y₂ )
- Slope of the line that passes through the points A ( -3 , -1 ) & B ( 0 , 3 )
~Plug the known values and then simplify !

If 1 mile is equal to 1.6 km, then our dimensional analysis would be set up like this to solve for m per hour: 
. The miles label cancels out leaving us with kkm per hour. Doing that multiplication gives us 12.8 km in one hour. If she can go 12.8 m in one hour, then we multiply that by 2 to find out how far she can go in 2 hours. 12.8*2 = 25.6 km in 2 hours.
Answer:
the answer is c
Step-by-step explanation:
4x = 4 x 2=8
8+12=20
