Answer 2

Answer:

i. 550 = 550

ii. (-7) = (-7)

Step-by-step explanation:

i. (-25) x [(-7) + (-15)] = [(-25) × (-7)] + [ (-25) × (-15)]

(-25) × [(-7) - 15] = 175 + 375

(-25) × (-22) = 550

550 = 550

Hence, proved

ii. (-7) x [(-8) + 9] = (-7)× (-8)] + [(-7) x 9]

(-7) × 1 = 56 + (-63)

(-7) = 56 - 63

(-7) = (-7)

Hence, proved
