A palindrome is a number that reads the same forward and backward. For example. 2442 and 111 are palindromes. If 5-digit palindr
german

Answer:

(E) 27

Step-by-step explanation:

Let the 5 digit palindrome be PQRQP

Since each digit is chosen from 1,2,3 therefore

P can either be 1,2 or 3 which gives us 3 options.

Q can also either be 1,2 or 3 which gives us 3 options

R can either be 1,2 or 3 which also gives us 3 options

So we have 3^3 = 3*3*3

= 27

This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.

Show how to use the greatest common factor of 84 and 72 to rewrite 84m - 72n as a product of two factors
slamgirl [31]

Answer:

The simplified expression is: 12(7m - 6n)

Step-by-step explanation:

Greatest common factor between 84 and 72

We keep dividing 84 and 72, while they can be divided by the same factor. So

84 - 72| 2

42 - 36|2

21 - 18|3

7 - 6

So the greatest common factor is 2*2*3 = 12.

Rewrite 84m - 72n as a product of two factors

Evidencing 12

84m - 72n = 12(\frac{84m}{12} - \frac{72n}{12}) = 12(7m - 6n)
