Simplify.7[-7 + 7(-3 + 6)]

A. -28 B. 0 C. -4 D. 98

Provide an appropriate response.Solve the following linear programming problem using the simplex method:MaximizeP = 7x1 + 2x2 + x3subject to:  x1 + 5x2 + 7x3 ? 8 x1 + 4x2 + 11x3 ? 9 x1 , x2 , x3 ? 0

A. Max P = 56 when x1 = 8, x2 = 0, x3 = 0 B. Max P = 9 when x1 = 1, x2 = 1, x3 = 0 C. Max P = 63 when x1 = 9, x2 = 0, x3 = 0 D. Max P = 0 when x1 = 0, x2 = 0, x3 = 8

Find the product.(x + 3)(x2 - x + 9)

A. x3 + 4x2 + 12x + 27 B. x3 + 2x2 + 27 C. x3 + 27 D. x3 + 2x2 + 6x + 27
