The answer is C. Once you add the like terms x^2 and 4x^2 you get your answer.
It’s b because it’s -85 f so the planet is colder
Answer:
x^4 -x^3 -9x^2 -11x -4
Step-by-step explanation:
We can use the zero product property
(x-a) (x-b) (x-c) (x-d) where a b c d are the roots
(x- -1)(x- -1)(x- -1) ( x-4) since the root -1 is repeated 3 times and 4 is a root
(x+1)(x+1)(x+1) ( x-4)
Foil the first two terms and the last two terms
(x^2 + 2x+1)( x^2 -3x-4)
Foil again
x^4 -3x^3 -4x^2 +2x^3 -6x^2 -8x +x^2 -3x-4
Combine like terms
x^4 -x^3 -9x^2 -11x -4
Answer:
30square tiles will be used to cover the floor
Step-by-step explanation:
Given:
Number of tiles to be red = 6/10
Total number of tiles used =18
To Find:
how many square tiles will be used to cover the floor = ?
Solution:
Let the number of square tile used to cover the floor be x
Then
x = 30
Isolate the k. Note the equal sign. What you do to one side, you do to the other.
First, subtract 2m from both sides
8k + 2m (-2m) = 3m (-2m) + 4
8k = m + 4
Next, divide 8 from both sides
(8k)/8 = (m + 4)/8
k = (m + 4)/8
k = m/8 + 1/2
k = m/8 + 1/2 is your answer
hope this helps
