Question

Que debo hacer díganmelo por favor?

Answer 1

Respuesta:

Explicación paso a paso:

3A + 2B = (3 × 5) + (2 × 2) = 15 + 4 = 19

2A - 5B = (2 × (-4)) - (5 × 3) = -8 - 15 = -23

2B - 4A = (2 × 3) - (4 × 2) = 6 - 8 = -2

(A + B)² = (3 + 1)² = 4² = 16

(4A - 5B)² = {[(4 × (-6)] - [5 × (-2)]}² = {[-24 - (-10)]}² = [(-24 + 10)]² = (-14)² = 196
