Question

2. Simplifique as expressões algébricas:
a) 4m + 10y + 3y - 2m + 25= *
2m + 13y + 25
4m + 13y + 25
6m + 13y + 25
b) 10n +12m - 9m + 5n + 2 + 26 *

15n + 3m + 22
10n + 4m + 26
15n + 3m + 28
c) 4d + 2y − d + 3y = *
5d + 5y
4 + 5y
3d + 5y

Answer 1

Resposta:

a)(4-2)m+(10+3)y+25= 2m+13y+25

b)(10+5)n+(12-9)m+28=15n+3m+28

c)(4-1)d+(2+3)y=3d+5y

Answer 2

a) 2m +13y + 25

b) 15n + 3m + 28

c) 3d + 5y
