Answer:

4, 1

Step-by-step explanation:

If you take 2, 8 and make it a ratio you get 2 : 8.

Then you turn 2 : 8 into 1 : 4. That is your answer for a mile.

For the other answer, you want to divide 2 by 8.

(Hope this helps) :)

Multiple the polynomials (3x^2+4x+4) (2x-4)
natali 33 [55]

Answer:

6x³ - 4x² - 8x - 16

Step-by-step explanation:

Step 1: Distribute the 2x

6x³ + 8x² + 8x

Step 2: Distribute the -4

-12x² - 16x - 16

Step 3: Combine the 2 distributions

6x³ + 8x² + 8x - 12x² - 16x - 16

Step 4: Combine like terms

6x³

8x² - 12x² = -4x²

8x - 16x = -8x

-16

Step 5: Rewrite

6x³ - 4x² - 8x - 16
