Answer:

Distributive property (Reversed)

Step-by-step explanation:

With the distributive property, it is possible to simplify expressions that consist of an expression term such as (a + b) being multiplied by one singular term such as c given as follows

c ×(a + b) = c·a + c·b

Factoring, which is the reverse  use of the distributive property enables the difference or the sum of two products, each having a common factor to be the presented as the difference  or the sum of two numbers multiplied by the common factor as follows;

2·x - 2·y = 2·(x - y).

I’m a right triangle the length of the hypotenuse is 12and the length of one leg is 8 . What is the length of the other leg?
denis23 [38]

Answer:

other leg is 8.94

Step-by-step explanation:

Pythagorean Theorem  is a² + b² = c²

a and b are legs

c is the hypotenuse

8² + b² = 12²

64 + b² = 144

-64          -64

        b² = 80

        √b² = √80

         b ≈ 8.94
