The problem asks us to multiply $2.9m$ by $(m-6)$. This involves using the distributive property.

1. Problem Description

The problem asks us to multiply $2.9m$ by $(m-6)$. This involves using the distributive property.

2. Solution Steps

We need to distribute $2.9m$ to both terms inside the parentheses $(m-6)$.

$2.9m(m-6) = 2.9m \cdot m - 2.9m \cdot 6$

First, multiply $2.9m$ by $m$:

$2.9m \cdot m = 2.9m^2$

Next, multiply $2.9m$ by $6$:

$2.9m \cdot 6 = 2.9 \cdot 6 \cdot m = 17.4m$

Therefore,

$2.9m(m-6) = 2.9m^2 - 17.4m$

3. Final Answer

$2.9m^2 - 17.4m$
