Answer 2

Answer:

Step-by-step explanation:

a composite number is any number which has factors except 1 and itself.

We know that every even number except 2 is a composite number.

Also, the product of two or more odd numbers will always be odd.

now, 7 x 11 x13 +13 = 13 (7 x 11 + 1)

since 7 and 11 are odd numbers 7 x11 will be an odd number 77. 77+1=78 which is an even number other than 2.Therefore, it is a composite number.

now, 7 x 6 x s x4x3x2

As every number when multiplied with 2 gives us a even and composite number, thus the answer.
