Answer 1

Misal bilangan tersebut:

• x dan x + 1

x + x + 1 = 43

2x + 1 = 43

2x = 43 - 1

2x = 42

x = 42/2

x = 21 (bilangan pertama)

x + 1 = 21 + 1 = 22 (bilangan kedua)

Hasil kali

= 22 × 21

= 462

• opsi c

Answer 2

Jawaban:

a + a + 1 = 43

Maka:

2a + 1 = 43

2a = 43 - 1

2a = 42

a = 42/2 = 21

a + 1 = 21 + 1 = 22

Kesimpulan:

hasilnya 21 × 22 = C. 462
