Commutaive property says
ab=ba or expanded to say
abc=cba
associative peropty =
a(bc)=(ab)c
so using that
first mix them up knowing that we can move the parenthaseese
all possible equivelnt ones are
4*(5*3)
(3*5)*4
3*(5*4)
(3*4)*5
3*(4*5)
If your still using number blocks then it is 20 ones but if its just addition or so it is just 20
Your reasoning and your answer were both correct. Discuss with the teacher. ("Discuss". DON'T fight.)
Answer:
60 km/hr
Step-by-step explanation:
100+100
