Robert is preparing a poster board presentation. He wants to make a decorated pattern with 10 squares to fill part of the poster. The area of the poster board is 720 in.² defined out how much space Robert will have left for his presentation he if he use the squares with 7 inch sides Evaluate 720-10S2, when S equals seven

To evaluate the expression, plug in the value of S:

720 - 10(7^2)

Simplifying,

720 - 10(49)

720 - 490

= 230

Therefore, Robert will have 230 square inches left for his presentation.

To find out how much space Robert will have left for his presentation, we need to calculate the area of the 10 squares and subtract it from the total area of the poster board.

Step 1: Find the area of one square.
The formula to find the area of a square is A = S^2, where S is the length of one side of the square.
In this case, S = 7 inches.
So, the area of one square is A = 7^2 = 49 square inches.

Step 2: Calculate the total area of the 10 squares.
Since there are 10 squares, we multiply the area of one square by 10.
Total area = 49 square inches * 10 = 490 square inches.

Step 3: Calculate the remaining space for the presentation.
To find the remaining space, we subtract the total area of the squares from the total area of the poster board.
Remaining space = Total area of the poster board - Total area of the squares
Remaining space = 720 square inches - 490 square inches
Remaining space = 230 square inches.

Therefore, Robert will have 230 square inches of space left for his presentation.

To find out how much space Robert will have left for his presentation, we need to calculate the area of the 10 squares and subtract it from the total area of the poster board.

The formula to find the area of a square is A = S^2, where A is the area and S is the length of a side.

Given that S = 7 inches, we can substitute it into the formula: A = 7^2 = 49 square inches.

Now, to find the area covered by the 10 squares, we multiply the area of one square by 10: 10 * 49 = 490 square inches.

To determine the space left for the presentation, we subtract the area covered by the squares from the total area of the poster board: 720 - 490 = 230 square inches.

Therefore, Robert will have 230 square inches of space left for his presentation.
