Answer:
SOLUTION :
Given equations are i) (-25) x [(-7) + (-15)] = [(-25) x (-7)] + [(-25) x (-15)]
ii) (-7) x [(-8) + 9] = [-7 x (-8)] + [(-7) x 9]
Now verify the given equations.
i) (-25) x [(-7) + (-15)]=[(-25) x (-7)] + [(-25) x (-15)]
LHS (-25) x [(-7) + (-15)]
=(-25)\times [-22]=(−25)×[−22]
(-25) x [ (-7) + (-15)] =550(−25)x[(−7)+(−15)]=550 =LHS
RHS [(-25) x (-7)] + [(-25) x (-15)]
=175+375
[(-25) x (-7)] + [(-25) x (-15)]=550=RHS
∴ LHS=RHS
∴ (-7) x [(-8) + 9] = [-7 x (-8)] + [(-7) x 9]
Hence verified.

Step-by-step explanation:
RHS= (-25) x [(-7) + (-15)]
= (-25) x (-7-15)
= (-25) x (-22)= 550
LHS= [(-25) x (-7)] + [(-25) x (-15)
= 175+375=550
therefore LHS=RHS
