Question

calcula aplicando la propiedad distributiva a)76-51)x42 b) (93-52)x6 c) (101-30)x8 d) (384-34)x37

Answer 1

a x (b + c) = (a x b)+ (b x c)    --->  (Propiedad distributiva)

(76 - 51) x 42 = (42 x 76) - (42 x 51)
(25) x 42 = 3192 - 2142
1050 = 1050
 
(93 - 52) x 6 = (6 x 93) - (6 x 52)
(41) x 6 =  558 - 312
246 = 246

(101 - 30) x 8 = (8 x 101) - (8 x 30)
(71) x 8 = 808 - 240
568 = 568
 
(384 - 34) x 37 = (37 x 384) - (37 x 34)
(350) x 37 =  14208 - 1258
12950 = 12950
