Answer:

60480

Step-by-step explanation:

This question has to do with permutations. A permutation is used to find the number of possible outcomes, assuming order matters. In this case, n=9 and r=6. This is written as $_{9}P_{6}$ which equals $\frac{9!}{(9-6)!}$ . Then, plug this into a calculator to get 60480.

Write two polynomials with a difference of 2x2 + x + 3

Anettt [7]

Answer:

The two polynomial CAN be $5x^4+5x^3+8x^2+x+6$ and $5x^4+5x^3+8x^2+2x+13$ .

Step-by-step explanation:

Step 1: Simplify the expression:

$2*2 + x + 3$

$4+x+3$

$x+7$

Step 2: Think of a random polynomial:

$5x^4+5x^3+8x^2+x+6$

Step 3: Either add your "random polynomial" by $x+7$ or subtract it.

I want to add it so...

$5x^4+5x^3+8x^2+x+6+x+7$

= $5x^4+5x^3+8x^2+2x+13$

Check by subtracting $5x^4+5x^3+8x^2+x+6$ and $5x^4+5x^3+8x^2+2x+13$ .

$5x^4+5x^3+8x^2+2x+13$

- $5x^4+5x^3+8x^2+x+6$

Marks's dad drove 123 miles in 2 hours. At that rate, how many miles would he drive in 5 hours?

mihalych1998 [28]

Answer:

307.5

Step-by-step explanation:

He drove 123 miles in 2 hours. If you go 100 miles in 2 hours that means you went 50 miles in one hour right? Using the same logic we can convert 123 miles in 2 hours to 61.5 miles per hour and then multiply it by 5.
