What males the set of integers different from the set of whole number ?

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

Solve the equation -9p - 17 =10 a -3 b. 16 c. 18 d -16
