Answer 1

Respuesta:

A) -a

B) 6m

C) -4p - 2

D) 2b + 1

E) 15m

F) 3xy

Explicación paso a paso:

A) 3a - 4a =  -a

a(3 - 4) = a( -1 ) = -a

B) 4m - 3m + 5m = 6m

m( 4 - 3 + 5) = m(6)= 6m

C) 2p - p - 3 - 5p + 1 = -4p - 2

= p( 2 - 1 - 5) +1 -3

= p(-4) -2

= -4p - 2

D) 5a + 2b + 1 - 3a - 2 a =  2b + 1

= a(5 - 3 - 2) +2b +1

= a(0) +2b + 1

= 2b + 1

E) 4m + 5m +7m - m = 15m

= m( 4 + 5 + 7 - 1)

= m(15)

= 15m

F) 2xy + 6xy - 5xy =​ 3xy

= xy(2 + 6 - 5)

= xy(3)

= 3xy
