Answer 1

Respuesta:

( −2+1 8−3+2 + −9 3 )(3−5)−9( 15 −2−1 ) =( −1 8−3+2 + −9 3 )(3−5)−9( 15 −2−1 ) =( −1 5+2 + −9 3 )(3−5)−9( 15 −2−1 ) =( −1 7 + −9 3 )(3−5)−9( 15 −2−1 ) =( −1 7 +−3)(3−5)−9( 15 −2−1 ) = −22 7 (3−5)−9( 15 −2−1 ) = −22 7 (−2)−9( 15 −2−1 ) = 44 7 −9( 15 −2−1 ) = 44 7 −9( 15 −3 ) = 44 7 −(9)(−5) = 44 7 −(−45) = 359 7
