The only positive even prime number is 2.

Any number divisible by 2 is by definition an even number.

So, if a number is divisible by an even prime (i.e., 2), it must be even.

Explanation

Bats are mammals, and like all mammals (except monotremes), they give birth to live young.

Turtles, crocodiles, and snakes are egg-laying reptiles.

Explanation

Given:

x + y = 3 ... (1)

y + z = 6 ... (2)

Subtract (1) from (2):

(y + z) - (x + y) = 6 - 3

z - x = 3

x - z = -3

Explanation

Boiling, chlorination, and filtration are all effective methods for making water safe to drink.

These processes remove or kill harmful bacteria, viruses, and impurities from drinking water.

Explanation

Tireless means تھکے ہوئے بغیر بڑی کوشش دکھا رہا ہے

Exhausted means مطلب انتہائی تھکا ہوا یا خراب ہونا

Explanation

Let's denote the length as L and width as W.

Given W = 0.75L or W = (3/4)L

Perimeter = 2(L + W) = 42

2(L + 3L/4) = 42

2(7L/4) = 42

7L/2 = 42

7L = 84

L = 12

W = (3/4)*12 = 9

Area = L * W = 12 * 9 = 108

Explanation

Given:

ab = -5

Possible integer pairs:

(a, b) = (5, -1), (-1, 5), (1, -5), (-5, 1)

Given a - b > 0:

Only (5, -1) and (1, -5) satisfy this.

For (5, -1):

a > -1 is true, and b is odd is true.

For (1, -5):

a > -1 is true, and b is odd is true.

In both cases, |a| ≠ 5 for one of the cases.

Explanation

Given:

36xy = 18xyz

Divide both sides by 18xy:

2 = z
