They all have 4 sides
Hope this is the answer you are looking for :)
36:38 which would be simplified as 18:19
Answer:
12X^-3
Step-by-step explanation:
12X^15 / 3X^12 = 0. The properties of exponents would say that we have to subtract the exponents in division, but we need the same bases first. In order to get the bases the same we need to divide both sides by 1/4. That will make 12 stay 12 and 3 become 12. Now we subtract the exponents using the properties of exponents with the same base. We end up left with 12x^-3.
I apologize if I made an error. I would be careful since I'm not to sure about my answer myself.
-25 is an integer and a rational number.
<h3>What is number system?</h3>
- A system of writing numbers is known as a number system.
- It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set.
- It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.
Now,
- Natural numbers are positive integers with a range of 1 to infinity; nevertheless, they do not include zero. -25 wouldn't be a natural number because it is a negative number.
- A group of numbers known as a whole number consists of all positive integers and 0. This wouldn't be a whole number because -25 isn't a positive number.
- Any real number that cannot be represented as the quotient of two integers is said to be irrational. Square roots of irrational numbers are also frequently seen. -25, however, is not a square root.
- Any number that can be expressed as a ratio, or a fraction, of two integers, is referred to be a rational number. Fractions, decimals, negative decimals, and other rational numbers are very prevalent. Since -25 can be represented as a ratio of two numbers. it is a rational number.
- A whole number that can be either positive, negative, or zero is known as an integer. As -25 is negative and a whole number( when positive), it is an integer.
Hence, -25 is an integer and a rational number.
