b.189 = 189

c.-2240 = 2240

it is not equal

Answer 2

Answer:

a)360=360

b)189=189

c)in this part I think you have missed the -sign on the rhs for 112...but if there is a - sign then the ans would be -2240= -2240

Step-by-step explanation:

a)by the associative property...if you multiply 8 by 9 it will give you 72 and then multiplying it by 5 will give you 360 and in the same way when you multiply 9 by 5 which gives you 45 and then 45 by 8, it will also give you 360,so RHS=LHS.

b) same property used as the first one
