Standard form is just the number. The answer is 405.
The greatest number of boxes of rice cakes would be 5, because when you take $10 and divide it by how much every box would cost it would be 5.13. However, boxes are sold in wholes and you must round down to get the greatest whole number of boxes he can get, which would be 5 boxes of rice cakes.
4x² - (2x + 3)²
4x² - (2x + 3)(2x + 3)
4x² - (2x(2x + 3) + 3(2x + 3))
4x² - (2x(2x) + 2x(3) + 3(2x) + 3(3))
4x² - (4x² + 6x + 6x + 9)
4x² - (4x² + 12x + 9)
4x² - 4x² - 12x - 9
-12x - 9
-3(4x) - 3(3)
-3(4x + 3)
