Question

Hola!! Me ayudan en esto? Les daré corona y corazón a la respuesta que este bien :"3
(3a + 15b) + (19a + 8b) =
(10x – 7y) + (4x – 11y) =
(12w + 23x) – (33w + 15x) =
(6c – 9d) + (18c + 16d) =
(2x + 3y) – (6x – 10 y) =


son expresiones algebraicas :"0

Answer 1

Respuesta:

a)

$\left(25\right)+\left(-7\right)+\left(-19\right)\\\\\\3a+15b+19a+8b\\\\\\3a+19a+15b+8b\\\\\\22a+15b+8b\\\\\\22a+23b$

b)

(10x – 7y) + (4x – 11y)

10x-7y+4x-11y

10x+4x-7y-11y

14x-7y-11y

14x-18y

c)

(12w + 23x) – (33w + 15x)

$12w+23x-\left(33w+15x\right)$

12w+23x-33w-15x

-21w+8x

d)

(6c – 9d) + (18c + 16d)

6c-9d+18c+16d

6c+18c-9d+16d

24c-9d+16d

24c+7d

e)

(2x + 3y) – (6x – 10 y)

2x+3y-(6x – 10 y)

2x+3y-6x+10y

-4x+13y
