Question

Q2. Simplifique as expressões a seguir. a) 4(3 + t) - 2t + 3 = b) 3y + 2 - y + 4y + 2x = c) 2x + 2y - 8x + y = 1 + 2 ++ d) V2C - V5C + 2 +2x . e) z 2 + 3 – 3z 2+ 2z²y =​

Answer 1

Resposta:

a) 4(3 + t) - 2t + 3 = 12 + 4t - 2t + 3= 2t + 15

b) 3y + 2 - y + 4y + 2x = 2x + 6y +2

c) 2x + 2y - 8x + y = 1 + 2 --> -6x + 3y - 3 = 0

d) V2C - V5C + 2 +2x = -3VC + 2x + 2

e) z 2 + 3 – 3z 2+ 2z²y = 2z²y +2z-6z +3 = 2z²y - 4z + 3
