Question

tolong bantu jawab pliss nnti ku follow dan ku kasi poin banyak
tapi pakai jalan ya plisss!!​

Answer 1

Penjelasan dengan langkah-langkah:

Nomor 4

(2x - 2) (x + 5)

= 2x.x + 2x.5 - 2.x - 2.5

= 2x² + 10x - 2x - 10

= 2x² + 8x - 10 → (c.)

Nomor 7

(2(3x + y))/x + (4(2x - y))/3x

= (6x + 2y)/x + (8x - 4y)/3x

= ((6x + 2y)/x × 3/3) + ((8x - 4y)/3x × 1/1

= (18x + 6y)/3x + (8x - 4y)/3x

= (18x + 8x + 6y - 4y)/(3x)

= (26x + 2y)/(3x) → C

Sisanya g bsa fotony tdk jls.

koreksi.
