3m+2n-m+2=2m+2n+2=2(m+n+1)
5x-3y+3x+3y=5x+3x=8x
6c-3d+c-1=7c-3d-1
Объяснение:
3m+2n-m+2
Итак, начинаем решать.
Приводим подобные члены:
2m+2n+2
Разложим выражение на множители и выносим за скобки общий множитель "2".
2(m+n+1)
5x-3y+3x+3y=5x+3x=8x
Сокращаем противоположные слагаемые и приводим подобные члены. ( то что подчеркнуто это и есть эти противоположные слагаемые):
5x-3у+3x+3у
Поскольку сумма двух противоположных величин равна 0, надо удалить их из выражения и получается такое выражение:
5х+3х
Теперь приводим подобные члены и упрощаем выражение:
8х
6с-3d+c-1
Приводим подобные члены:
7с-3d-1
The towel on the wall… It’s our ancient custom. There was not a single Ukrainian house , which would not be decorates with towels. A house without a towel was compared with a family without children. A towel symbolized not only aesthetic taste , it was a face of a house and of a hostess. The towels proved that the hostess was tidy and hard-working.
A newly-born child was handed with the towel, guests were met with bread and salt on the towel. A son , a husband, a father were seen off with the towel. While getting married the newly-formed family was standing on a towel too. Bread and salt on an embroidered towel were a symbol of hospitality of the Ukrainian people. To take the towel , to kiss bread symbolized unity, peace, love , understanding among people. This custom has a good tradition in our country.
Towel were used in different ceremonies and in everyday life as well: for wiping a face and hands, for drying dishes, for decorating the houses, for presenting dear people. The ornaments and colours of towels were different in different regions. A lot of songs about the embroidered towel have been created in Ukraine. Объяснение:
