Which equation can be used to solve for the value of x in the diagram? x + 40 + 115 = 180

40 + x = 115

x + 40 = 90

x = 40

△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 .

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

It says factor each expression completely 8y+48
