b. a^2 - b^2n = (a + b)(a - b)
c. a^3 + b^3 = (a - b) (a^2 - ab + b^2)
d. a^3 + b^3 = (a - b) (a^2 + ab + b^2)

Which of the following would represent the sum of 3 consecutive integers if x is the first integer?

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
