D is the only viable answer among these, as A, B, and C all contain two even integers which, by definition, have a greatest common factor of 2.

Correction: I was incorrect in saying that all even integers have a greatest common factor of 2; 2 is at least guaranteed to be one of the common factors in any group of even numbers, but these examples all have it as their greatest common factor as well.

Use the permutation formula to solve a problem when n = 15 and r = 4.

barxatty [35]

$nPr = \frac{n!}{(n - r)!}$

$15P4 = \frac{15!}{(15 - 4)!} = \frac{15!}{11!} \\ = \frac{15 \times 14 \times 13 \times 12 \times 11!}{11!} \\ 15 \times 14 \times 13 \times 12 = 32760$

To solve 49^3x = 343^2x+1, write each side of the equation in terms of base DONE

Nostrana [21]

Answer:

no solution

Step-by-step explanation:

49^3x = 343^2x+1

49 = 7^2 and 343 = 7^3

7^2 ^3x = 7^3 ^2x+1

we know that a^b^c = a^ (b*c)

7^(2 *3x) = 7^(3 *(2x+1))

7^(6x) = 7^(6x+3)

The bases are the same so the exponents have to be the same

6x = 6x+3

Subtract 6x from each side

0 =3

This is never true so there is no solution
