Question

tolong di jawab??jangan ngasal​

Answer 1

Jawab:

a. keliling = panjang lintasan

                = (x+1) + (4) + (5) + (1) + (2x-1) + (2x) + (2x-1) + (5)+ (x+1)+(2x)+(3)

                = x+2x+2x+2x+x+2x+1+4+5+1-1-1+5+1+3

                = 10x + 18

       

b.        48 = 10x+18

         10x = 48-18

               = 30

            x = 3

Penjelasan dengan langkah-langkah:

jelas.

Answer 2

Jawaban:

a. P = 10x + 18

b. x = 3 m

Penjelasan dengan langkah-langkah:

a.

P = x + 1 + 4 + 5 + 1 + 2x - 1 + 2x + (4 + 2x - 1) + (x + 1 + 5 + 2x - 1)

P = 2x + 2x + x + 1 + 4 + 5 + 1 - 1 + (4 + 2x - 1) + (x + 1 + 5 + 2x - 1)

P = 5x + 10 + (2x + 3) + (3x + 5)

P = 5x + 10 + 2x + 3 + 3x + 5

P = 5x + 2x + 3x + 10 + 3 + 5

P = 10x + 18

b. if the parameter is 48m then, x?

P = 48m

P = 10x + 18

10x + 18 = 48 m

10 x = 48 - 18

10x = 30

x = 3m
