simplifique as expressões

a-15z+3-9Z
b-7•x (x+4)-16
c-9a+5-8+7a
d-5•(4b-3)-37b
e-54q+18+2 (5-7w)
f-(8+6t)•5-(27t-3)+4​

Answer 1

Explicação passo-a-passo:

a) 15z + 3 - 9z

6z +3

b) 7×x (x+4) - 16

7x² + 28x - 16

c) 9a + 5 - 8 + 7a

16a - 3

d) 5(4b-3) - 37b

20b - 15 - 37b

-17b - 15

e) 54q + 18 + 2(5-7w)

54q + 18 + 10 - 14w

54q + 28 - 14w

f) (8+6t) × 5-(27t-3) + 4

40 + 30t - (27t - 3) + 4

40 + 30t - 27t + 3 + 4

47 - 3t
