Question

Na figura abaixo, temos DE//BC

Answer 1

a) x/4 = 12/6

6 * x = 4 * 12

6x = 48

x = 48/6

x = 8

b) 12/16 = 12 + 6 / y

12/18 = 18/y

12 * y = 18 * 18

12y = 324

y = 324 / 12

y = 27

c) 12 + 6 + 27 + 4 + 8 = 57

d) 4 + 16 + 6 + 27 = 53

Answer 2

Resposta:

Explicação passo-a-passo:

a) x/4 = 12/6

x.6 = 4.12

6x = 48

x = 48/6

x = 8

b) x/16 = 12/ y (x=8)

8.y = 12.16

8y = 192

y = 192/8

y = 24

c)(x+4) + (12+6) + (y) =

(8+4) + (18) + (24) =

12 + 18 + 24 =

p = 54

d) 4 + y + 16 + 6 =

4 + 24 + 16 + 6 =

p = 50
