Which auser explains why
the sum of 12+12
12+12 is an even
number?

An even number is a number that can be divided into two equal halves.

Also even numbers end in one of these digits: 0, 2, 4, 6, or 8

12 + 12 + 12 + 12 = 48

48 with the digit 8

48 divided in half gives two equal halves:

48/2 = 24

The number 24 can be added twice to check that the answer is correct:

24 + 24 = 48

So to summarize:

The sum of 12 + 12 + 12 + 12 is an even number because it can be equally divided in two halves and it ends in the digit 8.

hope this helps and please make me brainliest if it did :)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

congruent segments
