6
A y = x - 2x + 4
B. y = (x-3)(x-6)
C
C. y = (x+5)(x-4)
D. y = x2 + 9x +18

Respuesta :

Answer:

ecall that 6 + 6 + 6 = 6 × 3

Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.

Similarly,

6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42

Still by the same token,

2 + 2 + 2 + 2 = 2 × 4
