“The perimeter P of a triangle is equal to the sum of the lengths of sides a,b, and c”

Kryger [21]

Answer:

1. Write the addition of "a", "b" and "c".

2. The equation is: $P=a+b+c$

Step-by-step explanation:

You know that P represents the perimeter of the triangle and a, b and c represent the sides of the triangle.

By definition, the sum is the result of an addition. Therefore, the statement "The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c”, indicates that the perimeter is obtained by adding the lengths of the sides of the triangle.

Knowing this, you can write the following equation:

$P=a+b+c$

How do you divide big numbers? like for example, 2,673 ÷ 486?

Dahasolnce [82]

The easiest way I know is to multiply the divisor by different numbers to see how many times it will go into the dividend. multiplying 486 by 2 or three and seeing which one gets closest.
