2) 276m - (172m + 14m); - 4) 262 + (13z-52) + z; 6) 42x + 45 + 8x + 45; 8) 204b + 30b + 6b+ 56. жения (302х + 546x) - (848x - 18​

Answer 1

Ответ:

2) 276m - (172m + 14m)=90m

4) 262 + (13z-52) + z=210+14z

6) 42x + 45 + 8x + 45=50x+90

8) 204b + 30b + 6b+ 56=240b+56

(302х + 546x) - (848x - 18) = (848x)-(848x-18)= 848x)848x+18=18
