3(5x) =
2(7x – 3) =
m (m – n) =
10 (+ 5 – 6n + 3x) =
5m ( 2n + 6m – 7x + 4 – 10n + 4c) =

Answer 1

.Respuesta:

.Resolución:

1. 3(5x)

= 3 . 5x

.Rpta = 15x

2. 2(7x - 3)

= 2 . 7x - 2 . 3

.Rpta = 14x - 6

3. m (m - n)

= mm - mn

mm = m²

.Rpta = m² - mn

4. 10 ( + 5 - 6n + 3x)

10 (5 - 6n + 3x)

= 10 . 5 + 10 ( -6n) + 10 . 3x

= 10 . 5 - 10 . 6n + 10 . 3x

.Rpta = 50 - 60n + 30x

5. 5m (2n + 6m - 7x + 4 - 10n + 4c)

2n + 6m - 7x + 4 - 10n + 4c: - 7x + 4c + 6m - 8n + 4

.Rpta = 5m ( - 7x + 4c + 6m + 4 - 8n)
