Write the Boolean Equation B

I need help with this   Simplify the Boolean expression (A+B+C)(D+E)' + (A+B+C)(D+E) and choose the best answer.         D'E'     A'B'C'     D + E     A + B + C    Give the relationship that represents the dual of the Boolean property A + 1 = 1? (Note: * = AND, + = OR and ' = NOT)     A * A = A     A * 1 = 1     A + 0 = 0     A * 0 = 0

Write the Boolean expression equivalent to the following logic circuit. Do not simplify! A D Y D
