My number has a tens digit that is 8 more than the ones digit. zero is not one of my digits. write the 2-digit number that matches the clues

The requested number is: 91

Numbers are quantities used in measurements

Numbers in mathematics can be divided into several terms

numbers consist of positive, negative and 0 numbers

numbers consisting of positive numbers, starting with number 1

a number consists of positive numbers and zeros

numbers that can only be divided by numbers themselves and the number 1

And examples of other numbers such as imaginary numbers, real numbers, rational numbers, etc.

Integers themselves consist of

the number to the right of the number 0 is 1,2,3 ...

the numbers to the left of the zeros are -1, -2, -3 ...

From the above questions we can separate into several sections:

Means the number requested consists of 2 numbers, let us suppose the tens = x and the ones = y, so the number is xy

we can translate this sentence into the equation:

x = y + 8

So from the numbers 0 to 9 that have a difference of 8 to fill the values of x and y are

because Zero is not one of my digits, the most appropriate numbers x and y are 1 and 9

So the number requested is

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
