Answer: 6*(5 + 2)
Explanation: We want to model the expression 30 + 12 = 42
the options are:
6*5 + 2
6 + 5 + 2
6 + 5*2
6*(5 + 2)
You can do it strait forward and solve each equation, and you will find the the right solution is 6*(5 + 2)
because if we took ur initial numbers, 30 and 12, and we divide both of them by 6 (taking 6 as a common factor) we have:
30 + 12 = 6*5 + 6*2
now we can use the distributive property, and we get:
30 + 12 = 6*5 + 6*2 = 6*(5 + 2)
