-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.

This is only my opinion. I could be wrong.
My guess is:
Somebody else used that book before you, maybe last year or
the year before, and it was somebody who didn't mind writing
in his book.
One day he didn't have time to write down the homework in his
assignment notebook, so he just circled the homework problems
in his textbook.
Answer:
Step 1 write the equation for perimeter (2L+2W =24)
Step 2 write the equation for area L x W = 32
Step 3 rewrite the equation of area so that one variable is on the right side L=32/W
Step 4 substitute L from step 3 into Equation 1 and simplify 2(32/W)+2W=24
Step 5 having found the width in step 4, use equation 3 to find the length
Step-by-step explanation:
<em>This is just added to show you how to solve but limit your answer to the answer above: rate brainliest please</em>
Area = L*W
Perimeter = 2(L+W)
So say L*W=32
and 2(L+W) = 24 which is 2L+2W =24
From area L=32/W
Then substitute it into perimeter
2(32/W)+2W=24 if you simplify this you get Width is 4 and 8
then length =32/W but W is 4 and 8 So L= 8 and 4
Meaning you have two options first rectangle is W=4 and L is 8, second triangle W=8 and Length=4
Answer:
y = 3^(x + 1).
Step-by-step explanation:
Here the y values are increasing by a factor 3 and when x = 0 y = 3,
so y = (3)^1 when x = 0 - that is y = (3)^(0 + 1) = 3.
So y = 3^(x + 1) is the rule.
Check: when x = -2, y = 3^(-2+1) = 3 ^-1 = 1/3.
When x = 1, y = 3(1+1) = 3^2 = 9.
