a. -18 + 35p – 12p?
b. 18 – 35p – 12p?
Č.-18 + 19p – 12p2
d. 18 – 19p – 12p?
5. Hasil kali dari (9-4p)(3p-2) adalah…
Jawaban:
-18 + 35p – 12p^2
Penjelasan dengan langkah-langkah:
9 x -2= -18
9 x 3p = 27p
-4p x -2 = 8p
-4p x 3p = -12p^2
Jadi, -18 + 27p + 8p – 12p^2
= -18 + 35p – 12p^2
Penjelasan dengan langkah-langkah:
(9-4p)(3p-2) = 9 x 3p – 9 x 2 – 4p x 3p – 4p x (-2)
= 27p – 18 – 12p^2 + 8p
= 35p – 18 – 12p^2
= -12p^2 + 35p – 18 ✔
