Quis g ada yg spcial [2/5]

Jawaban:

1) 54x²

2) x = -1/4

Penjelasan dengan langkah-langkah:

1) 6x(4x + 5x)

= 6x × 9x

= (6 × 9)x²

= 54x²

2) 8x + 4 = 2

8x = 2 – 4

8x = -2

x = -2/8

x = 1/4

Penjelasan dengan langkah-langkah:

1)

= 6x·(4x + 5x)

= 6x·9x

= 6·9(x·x)

= 54x²

2)

8x + 4 = 2

8x = 2 – 4

8x = -2

x = -2/8

x = 1/4
