Question

are 5 multilyed by 7h and 35h equvalent

Answer 1

If there was no h on 35 then it would be equivalent but, since there is an h and that represents multiplying then you would have to multiply 35 and 5.

Answer 2

yes because 7h means 7 times h
this is equivilent to 5 times (7 times h)
using the associative property whieh says a(bc)=(ab)c therefor
5 times (7 times h)=(5 times 7) times h
5 times 7=35 so
this equals
(5 times 7) times h=(35) times h=35h

so yes it is equivilent
