Question

A = {x: x satisfies x3 – 11x2 + 39x - 45 = 0}
B = {x: 5x – 6, 3x + 1, x – 1 are the lengths of the sides of a triangle) then number of A intersection B is​

Answer 1

Answer:

A = {x: x satisfies x3 – 11x2 + 39x - 45 = 0}

B = {x: 5x – 6, 3x + 1, x – 1 are the lengths of the sides of a triangle) then number of A intersection B is
