where is a poster board presentation he wants to make a decorative pattern with 10 squares to fill in the post of the area of the area of the poster is 720 inches how many how much space will Walmart have left for his presentation if he squares with 7 inches evaluate 720 - 10 + 2 when s equals 7

To determine how much space will be left for the presentation after using squares of size 7 inches, we first need to calculate the total area occupied by the 10 squares.

Each square has an area of:
\[
\text{Area of one square} = \text{side}^2 = 7^2 = 49 \text{ square inches}
\]

Now, to find the area occupied by 10 squares:
\[
\text{Total area of 10 squares} = 10 \times 49 = 490 \text{ square inches}
\]

Next, we subtract the total area of the squares from the total area of the poster:
\[
\text{Area left for presentation} = \text{Total area of the poster} - \text{Total area of 10 squares} = 720 - 490 = 230 \text{ square inches}
\]

Now, according to your question, you asked to evaluate the expression \(720 - 10 + 2\) when \(s = 7\). Let's calculate that as well:

Substituting \(s\) with 7:
\[
720 - 10 + 2 = 720 - 10 + 2 = 712
\]

So to summarize:
- The space left for his presentation is **230 square inches.**
- The value of \(720 - 10 + 2\) when \(s = 7\) is **712.**
