Answer» Step-by-step EXPLANATION: Let the no. be x and y x+ y= 50. (1) x-y= 14 x=14+y. (2) put 2 in 1 14+y+y= 50 14+2y= 50 2y= 36 y= 18 x+y=50 x+ 18= 50 x= 32 a3-b3= (a-b) (a2+b2+ab) = (32-18)[(18)^2 +(32)^2 + (32)(18)] = 14[ 324 +1024 + 576] = 14(1924) = 26936 Hope it helps Mark it as brainliest and Don't forget to follow me |
