A composite number is a positive integer that has at least one positive divisor other than one or itself. In other words, a composite number is any positive integer greater than one that is not a prime number.

Let’s evaluate the two expressions you provided:

5x3x11+11 can be simplified to 165 + 11 = 176.

5x7+7x3 can be simplified to 35 + 21 = 56.

Both 176 and 56 are composite numbers. We can see this by finding their divisors:

The divisors of 176 are 1, 2, 4, 8, 11, 16, 22, 44, 88, and 176. Since it has divisors other than 1 and itself, it is a composite number.

The divisors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. Since it has divisors other than 1 and itself, it is also a composite number.

So, both expressions evaluate to composite numbers.
