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

1 answer

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.
