The total of cannot counts - 110
Total number of boys - 263
Total number of girls - 244
The FULL total - 507
Rewrite it in the form a^2 - b^2, where a = 5x and b = 8
(5x)^2 - 8^2
Use the Difference of Squares; a^2 - b^2 = (a + b)(a - b)
<u>= C. (5x - 8)(5x + 8)</u>
.21 as a fraction would be 21/100
