Explanation

Swimming is a full-body workout that engages multiple muscle groups.

It leading to high energy expenditure.

It is often considered more energy-intensive than jogging, riding, or running due to the resistance of water.

Explanation

Given n(n + 1)(n + 5):

1. n(n + 1) is always even (multiple of 2) since it's the product of two consecutive integers.

2. For divisibility by 3:

    If n is a multiple of 3, the expression is divisible by 3.

    If n = 3k + 1, then n + 5 = 3k + 6 is divisible by 3.

    If n = 3k + 2, then n + 1 = 3k + 3 is divisible by 3.

Given these cases, n(n + 1)(n + 5) is divisible by 3.

Explanation

Given the operation a * b = a + b + 1:

Let's find the identity element 'e' such that a * e = a.

a * e = a + e + 1 = a

This implies e + 1 = 0, so e = -1.

Now, to find the inverse 'x' of 'a' such that a * x = e = -1:

a * x = a + x + 1 = -1

This implies a + x = -2.

x = -2 - a

x = -a - 2

Explanation

Let's directly evaluate the system of equations:

1x + 3y = 1

3x + λy = 3

For infinitely many solutions, these equations must represent the same line. Multiplying the first equation by 3 gives:

3x + 9y = 3

Comparing this with the second equation 3x + λy = 3, we see that λ must equal 9 for the equations to be identical.
