Answer 2

It looks like you want to simplify the expression $(2.5c + 7z)(72 - 2.5c)$. To do this, we'll use the distributive property (also known as FOIL - First, Outer, Inner, Last). Let's break down the steps:

1. Multiply the terms in the first parentheses with the terms in the second parentheses:

   $(2.5c) \cdot (72) + (2.5c) \cdot (-2.5c) + (7z) \cdot (72) + (7z) \cdot (-2.5c)$

2. Perform the multiplications:

   $180c - 6.25c^2 + 504z - 17.5cz$

So, the simplified expression is $180c - 6.25c^2 + 504z - 17.5cz$.
