Розкрити дужки -0.7(7l-2.1+5k)

Answer 1

To simplify the expression -0.7(7l-2.1+5k), we can use the distributive property of multiplication over addition. This property states that when we multiply a number by a sum of terms, we can distribute the multiplication to each term individually.

Let's break down the expression step by step:

-0.7(7l-2.1+5k)

First, distribute -0.7 to each term inside the parentheses:

-0.7 * 7l + -0.7 * (-2.1) + -0.7 * 5k

Simplifying each term:

-4.9l + 1.47 - 3.5k

So, the simplified expression is -4.9l + 1.47 - 3.5k.
