Question

Efectua las siguientes multiplicaciones

Answer 1

Explicación paso a paso:

a) 4 . (x + 2) / 2 = 4/2 . (x + 2) = 2 . (x + 2) = 2.x + 2. 2 = 2x+ 4

b) 12 . (-2x + 3) / 4 = 12/4 . (-2x + 3) = 3 . (-2x + 3) = -6x + 9 = 9 - 6x

c) 3x + 4/5 . 20 = 3x + 4 . 20/5 = (3x + 4) . 4 = 12x + 16

d) -6 . (x - 2)/3 = -6/3 . (x - 2) = -2 .  (x - 2) =  -2x + 4 = 4 - 2x

e) (-4x - 5)/2 . 10 = (-4x - 5). 10/2 = (-4x - 5) . 5 = -20x - 25

f) (3x - 2)/2 . (-10) = (3x - 2) . (-10)/2 = (3x - 2) . (-5) = -15x + 10 = 10 - 15x
